        Revert the Network Tab's text filter back to being just a URL filter with the

        This also renames the "text filter" to "url filter" everywhere in the ContentView
        for clarity. A follow-up change will make the url filter be case-insensitive
        to fully match the filter bars in other tabs.

        This helps straighten out async test() functions that need
        to test exceptional cases. Without this, every such method
        needs try/catch boilerplate to leak the error outside the
        scope of the catch-block and then assert that it exists.

        (TestHarness.prototype.expectException):
        Added. This method takes a callback which is expected to raise
        an exception either by throwing an Error instance or returning
        a Promise that rejects with an Error instance. The method returns
        a Promise that is either resolved with the expected exception
        from one of the above sources, or is rejected with the non-exception
        result that was returned or resolved by the callback.

        Fix the error handling. I added this at the last moment and failed to test. The logic is
        inverted, causing an error to always be reported on success.

        Add a missing 'mkdir -p' using File::Path::make_path. This has its own built-in error
        reporting, so no need to add our own.

        CanvasRenderingContext2D.webkitGetImageDataHD and webkitPutImageDataHD were never standardized,
        and Blink removed support in 2014 (https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/FOPH5dloGG8).

        ServiceWorker Inspector: Frontend changes to support Network tab and sub resources
        https://bugs.webkit.org/show_bug.cgi?id=179642
        <rdar://problem/35517704>

        Reviewed by Brian Burg.

        This patch makes use of the NetworkAgent and ServiceWorker agents in the frontend
        for a ServiceWorker inspection target. It also makes changes to ensure that the
        subresources requested by a ServiceWorker appear as expected in both the Resources
        and Network Tabs.

        The backends of ServiceWorkers and DedicatedWorkers for network requests are
        different, but we want the presentation to be very similiar. Ultimately we'd like
        to move to more similiar backends if possible.

        The first (after Inspector.enable) message a ServiceWorker inspector sends to the
        backend is ServiceWorker.getInitializationInfo. This parallels a Page inspector
        sending Page.getResourceTree. From the response we get enough information to
        setup the MainTarget with enough information (targetId, URL) to know what its main
        resource URL will be. Like DedicatedWorkers, the target's main resource will be
        filled in with the first WI.Script matching the URL. With this initialization
        message alone the ServiceWorker Target behaves almost identically to a Worker
        target and Network loads associated with the target (by targetId) are added as
        sub-resources as expected.

        The biggest tension in this patch is within FrameResourceManager. The class, as
        its name indicates, assumes page resources with Frames, navigation, and loader
        semantics. It takes a few modifications to make it better handle resources not
        associated with a Page. A follow-up will rename this to just ResourceManager as
        the class' main task is now to associate Resources with Targets.

        * UserInterface/Base/Main.js:
        (WI.loaded):
        There are assumptions in a few places that the main target is a Page. Those
        places can now be reached when the main target is a ServiceWorker. Add a
        convenience WI.pageTarget that can be used in these places.

        * UserInterface/Test/Test.js:
        (WI.loaded):
        Add pageTarget.

        * UserInterface/Controllers/DebuggerManager.js:
        (WI.DebuggerManager.prototype.scriptDidParse):
        Generalize the condition so the main target can have its main resource populated.
        This will be the case when a ServiceWorker is the main target and its main resource
        needs to be populated from a Script.

        * UserInterface/Controllers/FrameResourceManager.js:
        (WI.FrameResourceManager):
        (WI.FrameResourceManager.prototype._processServiceWorkerInitializationInfo):
        Handle ServiceWorker Resource initialization which is different from Page initialization.

        (WI.FrameResourceManager.prototype._addNewResourceToFrameOrTarget):
        (WI.FrameResourceManager.prototype._addResourceToTarget):
        (WI.FrameResourceManager.prototype._addFrameTreeFromFrameResourceTreePayload):
        Eliminate PageAgent, which might not be available in some targets.
        Use pageTarget instead of mainTarget where appropriate.

        * UserInterface/Controllers/TargetManager.js:
        (WI.TargetManager.prototype.targetForIdentifier):
        A ServiceWorker is the first time that the main target has an identifier,
        so let TargetManager find it by target id.

        * UserInterface/Models/Resource.js:
        (WI.Resource):
        (WI.Resource.resolvedType):
        (WI.Resource.prototype.updateForResponse):
        For Resource.Type.Other resources include a better type inferred from the MIME type.
        ServiceWorker loads currently don't have type information and this provides a great
        type for such loads. This should also provide nice types for CacheStorage.add*
        populated resources which are otherwise type-less fetches.

        * UserInterface/Protocol/Connection.js:
        Rename the class since this may no longer be a "Page".

        * UserInterface/Protocol/MainTarget.js:
        (WI.MainTarget):

        The implementations of DetailsSidebarPanel subclasses assume that panels
        are closed and released when no longer needed. Keeping them alive with

        CodeMirror was already combined for Main.html. We need to also combine CodeMirror for Test.html.

        When the first Recording is taken of a canvas, it is immediately added as a child. When the
        CanvasTreeElement is `attached`, however, it will attempt to regenerate its children if
        necessary. This is especially true for canvases with ShaderPrograms, as they are added with
        `addRepresentedObjectToNewChildQueue`, meaning that the child TreeElements aren't actually
        added until the next tick, preventing the ContentBrowser logic from generating path
        components correctly.

        This patch switches to using `addChildForRepresentedObject` so that there is no delay when
        adding children, and also ensures that any existing recordings are also added on regeneration.

        Before this change, the CanvasCollection was regenerated each time the Canvas tab was
        attached. This also caused the invisible TreeOutline, used for the path components and to
        manage selection, to be reset as well. Whenever the page refreshed, however, the old
        canvases, and associated recordings, were not removed. This patch reworks all of this logic

        Web Inspector: Canvas Tab: canvases overview should support navigation via keyboard

        Create a KeyboardShorcut for each of the following:
         - Up: selects the previous canvas in the selected column
         - Down: selects the next canvas in the selected column
         - Right: selects the next canvas in the selected row
         - Left: selects the previous canvas in the selected row
         - Space: toggle recording of the selected canvas
         - Shift+Space: toggle single-frame recording of the selected canvas

        The calculation for selected row/colum is based on the `offsetWidth` of the parent element
        and the selected item's content view element. Since this view uses a flexbox, all of the
        items are expected to have the same dimensions, meaning that this value is uniform. The
        intended functionality is that of a spreadsheet, where pressing pressing left/right will
        never change the selected row and up/down will never change the selected column.

        Web Inspector: Show recordings in CanvasTabContentView
        https://bugs.webkit.org/show_bug.cgi?id=177606
        <rdar://problem/34715819>

        Reviewed by Brian Burg.

        Original patch by Matt Baker <mattbaker@apple.com>.

        This patch folds canvas recordings into the new Canvas tab, which now
        supports showing both CanvasCollections and Recordings.

        When viewing recordings, a back button is shown at the start of the
        navigation bar, allowing the user to return to the overview. It has been
        styled with a back arrow, to make its function as clear as possible.
        Like other navigation path components, the item for the recording can
        clicked to select another recording taken from the same canvas.

        The recording action scrubber has been moved from the content browser's
        navigation bar to a more prominent location in the recording content view.
        Selecting a frame tree element in the navigation sidebar no longer selects
        the last action for that frame. This was changed to prevent the scrubber
        position from behaving non-monotonically when selecting actions in sequential
        order.

        While this patch retains support for importing recordings, the feature
        is not polished. Currently it is not possible to return to an imported
        recording after leaving closing the view. In the future we may want to
        consider including a navigation sidebar panel for the overview, which
        could list canvas recordings (and eventually shaders).

        Looking for special cases involving nodeIds is incorrect, as nodeIds need not be unique in the layer list (such

        this way shares no data with its predecessor, meaning that no consumer can act upon this so-called preservation.
        A preserved layer should be nothing more or less than a recycled layerId (the thing that *is* unique).

        filtering until the resource finishes loading.

        This patch adds experimental feature support for the Canvas tab. Initially
        the tab provides only an overview of the canvases in the page, and will
        exist side-by-side with the existing experimental Canvas UI.

        (WI.Canvas.prototype.requestSize):
        Use promises to retrieve canvas data asynchronously.

        * UserInterface/Models/CollectionTypes.js: Added.
        (WI.CanvasCollection):
        New location for concrete collection types. Having a class to type check
        makes using a collection as a represented object a bit simpler.

        (.content-view.canvas): Deleted.
        (.content-view.canvas > .preview): Deleted.
        (.content-view.canvas > .preview > img): Deleted.
        During the transition to the new Canvas tab, CanvasContentView needs to
        support being shown as a full-size content view, and as an item in a
        CollectionContentView. Hide header and footer elements by default.

        (WI.CanvasContentView.prototype.hidden): Deleted.
        (WI.CanvasContentView.prototype.closed): Deleted.
        (WI.CanvasContentView.prototype._showPreview): Deleted.
        Added new UI for display in the Canvas overview. These elements are always
        created, but only appear when the canvas is viewed as a "card".

        Canvas previews are no longer shown as soon as they are available from
        the backend. Instead, once the canvas content is ready a layout is scheduled.
        This guarantees that refreshing all canvases at once causes no flicker,
        and introduces no perceptible delay.

        Finally, the "Cancel recording" tooltip has been renamed "Stop recording",
        to match the behavior of the command.

        * UserInterface/Views/CanvasDetailsSidebarPanel.js:
        (WI.CanvasDetailsSidebarPanel.prototype._refreshSourceSection.this._canvas.requestNode.): Deleted.
        Canvas.prototype.requestNode now returns a promise.

        row. This can always reset the scrollTop to 0. Or when a large number of rows
        is reduced to a smaller number than our current scrollTop but still more than
        fit on one screen. In that case we can reduce the scrollTop to whatever would
        scroll the table to its max position.

        Table is mostly a re-implementation of DataGrid. Much of its functionality
        was a direct copy that was then modified and simplified for a smaller
        and simpler feature set.
        
        Table behaves more like Cocoa's NSTableView. A datasource supplies the
        number of rows, which Table uses to resize appropriately. A delegate is
        then called to populate cells in a row when they become visible. Table
        does minimal caching, and in the event of data source changes
        (resorting, adding rows, modifying rows, etc) the visible rows are
        simply recreated from scratch. Clients should therefore make generating
        a cell's contents as simple and performant as possible.

        Unlike DataGrid, rows are just an <li> with a bunch of cells. Since the
        number of rows are limited to (roughly) those that are visible, most
        operations, like resizing, creates / modifies each of the visible cells.

        Finally, Table's resizing operations behave more like flexible content
        than DataGrid's neighbor only approach. This makes resizing the table
        generally easier to do, but may need refinement to decide which columns
        we would prefer to distribute columns during resizing.

        The NetworkTableContentView has a Table and it is the table's data source
        and delegate. It contains a complete list of entries, and a filtered list
        of entries, which is the backing list of rows for the table. As entries
        are created, updated, or filters modified, this generally modifies
        entries, sorts, filters, and reloads the table. As much as possible it
        batches operations in the usual layout loop.

        This guarantees that a layout is always scheduled as soon as a view is

        Web Inspector: introduce an AppController class and shared instance of it
        https://bugs.webkit.org/show_bug.cgi?id=177024

        Reviewed by Matt Baker.

        WebInspectorUI currently has an app controller singleton that's distributed
        among many properties on the WI object, which also serves as a namespace for
        classes, enums, and other frontend objects. The singleton should be a proper
        class so that we can think more easily about what state is global.

        In the process of moving pieces of Main.js into AppController, I intend to move
        most UI related code into a view controller class for the top level view.
        AppController really shouldn't be doing anything to the view hierarchy or DOM.
        It is yet to be determined how responsibility for global DOM events, such as
        those for keyboard shortcuts, will be handled.

        This larger refactoring project will let us more easily do things like connect
        to multiple debuggables in the same Inspector instance, and switch between views
        of different debuggable targets. Even if this never comes to pass, the code will
        be a lot easier to reason about and maintain in the future.

        For the first patch, introduce {AppController, TestAppController} <: AppControllerBase.
        Shared code goes in the base class. In the Main.html and Test.html files, first
        construct the AppController and then call .initialize() to avoid cyclic dependencies
        on the global singleton WI.sharedApp.

        Web Inspector: make recording swizzle async
        https://bugs.webkit.org/show_bug.cgi?id=176936

        Reviewed by Joseph Pecoraro.

        Move all swizzle functions, and all logic that depends on swizzled values, to async
        functions so that await can be used to pause execution while objects load. This was
        necessary primarily for swizzling Image values, as the Image is not able to be used (such as
        for creating a CanvasPattern) until its "load" event has fired. Any callers of a Recording's
        actions getter must now adapt to working with a promise that will resolve once all swizzling
        has finished across all actions within that recording.

        Reviewed by Devin Rousso.

        This patch introduces a constant, `minimumContentBrowserWidth`, which
        constrains the maximum width of either sidebar:

        maxSidebarWidth = window.innerWidth - minimumContentBrowserWidth - otherSidebarWidth

        A value of 100px for `minimumContentBrowserWidth` leaves enough space for
        three NavigationItems at their minimum width (32px), with a few pixels
        left over for good measure. For most tabs this will ensure that the buttons
        for showing the sidebars will be visible, along with an addition button.

        Web Inspector: Critical content browser toolbar buttons are hidden at narrow widths
        https://bugs.webkit.org/show_bug.cgi?id=175999

        Reviewed by Devin Rousso.

        This patch adds a VisibilityPriority concept to NavigationItems. If a
        NavigationBar cannot fit all of its items in the available space, items
        are hidden to make room, starting with the lowest priority item. Consecutive
        dividers are then collapsed, as well as leading and trailing dividers.

        Reviewed by Devin Rousso.

        This patch adds frontend support for shader program instrumentation.
        The frontend creates a ShaderProgram model object for each WebGLProgram.
        Since only canvases with a WebGL context have programs, the Canvas model
        object does not contain any logic specific to programs. CanvasManager
        dispatches program added/removed events, and the parent Canvas can be
        accessed from ShaderProgram but not the other way around.

        Delay the creation of the spinner for 100ms.  If the content is available before then, just
        clear the timeout and the spinner will never be created/shown.

        We measured an average of 35ms to load and display images with slow cases being around 55ms.
        100ms was chosen for the timeout to give some room to allow for abnormally slow loading
        while not being too long as to be outright noticable.

        Calls the new protected function removeLoadingIndicator to ensure that the spinner (and any
        other element) is removed.

        This is necessary because TextResourceContentView effectively has two phases of loading its
        content: getting the content and formatting it for display.  The first follows the same path
        as the other ResourceContentView subclasses, the second waits for the ContentWillPopulate
        event on SourceCodeTextEditor before it actually adds the content as a subview.  In this
        case, the spinner should only be removed right before the content is actually added, not
        once it's ready.

        Reviewed by Matt Baker.

        Introduce RemoteObject.prototype.updatePreview which can be used to update
        the preview of a RemoteObject with a current view for the object. Currently
        we only use this to fetch the preview that we did not have for the `thisObject`
        in the scope chain sidebar. However this could be used generically to update
        a RemoteObject's preview (ObjectPreview) at any time.

        Every size increase of a resource causes a sidebar item to be re-attached to the DOM. Sending or
        receiving a WebSocket message causes a size increase. When size increase happens too frequently,

        In the Debugger sidebar, DOM breakpoints can be cleared from a DOM node
        in two ways: by using the DOM node tree element's context menu, or by
        pressing the delete key while the element is selected. Each method used
        a different code path, and the latter had an error which caused it to fail.

        Web Inspector: Make it easy to dynamically show/hide a SettingsView
        https://bugs.webkit.org/show_bug.cgi?id=171765
        <rdar://problem/32031280>

        Reviewed by Brian Burg.

        This patch adds SettingsTabContentView.prototype.setSettingsViewVisible,
        for dynamically showing/hiding a child view (and its NavigationBar item).
        The following new behavior is relevant when more that one child SettingsView
        exist in the Settings tab:
         - Hiding the selected view will cause a new view to become selected.
           The previous visible view is selected, if it exists. Otherwise the
           next visible view is used.
         - Showing a view when no views are selected cause the view to be selected.

        As the Settings tab currently has only one child view, the behavior above
        was tested by adding a handful of vanilla SettingsView objects to the tab
        and toggling their visibility.

        Web Inspector: RTL: inherit system layout direction by default
        https://bugs.webkit.org/show_bug.cgi?id=171402

        Reviewed by Joseph Pecoraro.

        Web Inspector's layout direction should follow the system layout direction
        by default now that most RTL bugs seem to be fixed. We are ready for more
        feedback.

        * UserInterface/Base/Main.js:
        * UserInterface/Base/Setting.js:
        Rename the existing "layout-direction" setting so that the new default
        value is set properly even for people who have overridden the layout
        direction while the setting was exposed to everyone.

        (WebInspector.GeneralSettingsView.prototype.initialLayout):
        (WebInspector.GeneralSettingsView.prototype.layout):
        (WebInspector.GeneralSettingsView):
        Make the layout direction override setting only visible when DebugUI
        is turned on. This remains only for engineers to quickly check layout bugs.

        * UserInterface/Views/SettingsView.js:
        (WebInspector.SettingsView.prototype.addGroupWithCustomSetting):
        (WebInspector.SettingsView.prototype.addCustomSetting): Deleted.
        Refactor the convenience method to return both the group and the
        custom setting. This allows us to toggle .hidden on the entire
        row for the Layout Direction setting (label and editor).

        * Localizations/en.lproj/localizedStrings.js:
        Unlocalize the setting strings since they are only shown in engineering builds now.

        We need to flip the cancel and search icons, and flip padding

        I am still not happy with the title/subtitle ordering
        (i.e., the domain vs the resource name), but this issue will
        be solved primarily in the navigation sidebar first and then
        adjusted for Open Resource Dialog if those changes are not

        Calling increaseSize on a resource may cause a WebInspector.TimelineDataGrid#TimelineDataGrid#_refreshDirtyDataGridNodes call.
        Make sure _refreshDirtyDataGridNodes preserves selection of a treeElement.

        * UserInterface/Views/TimelineDataGrid.js:
        (WebInspector.TimelineDataGrid.prototype._refreshDirtyDataGridNodes):
        Re-attaching treeElement causes it to lose selection. Select it again after re-attaching.

        Web Inspector: RTL: add FindBanner support for RTL layout
        https://bugs.webkit.org/show_bug.cgi?id=168723

        Reviewed by Timothy Hatcher.

        Due to the large number of CSS tricks used by this widget, adding RTL
        support involves changing a large number of rules. The important parts:

        - Use '.segmented.{previous,next}-result' instead of '.segmented.
        {left,right}', this makes the style rules way less confusing for RTL.

        - Flip icons so icons look like "< >" but actions are reversed.

        - Get rid of the weird expanding button divider. This is impossible
        to mirror with the existing adjacent sibling combinator, and it does
        not match the system appearance. Just replace the mini-divider with a
        full divider and remove related dynamic rules that trigger on :active.

        - Always keep the button divider between next/previous on the rightmost
        button, to avoid subtle differences between LTR and RTL.

        - Fix some mistakes where we weren't using --border-color and also
        didn't adjust the handcoded border color for the inactive window case.

        New frontend manager for the DOMDebugger domain. A DOM breakpoint is
        described by a location (URL and node path) and type. The manager keeps
        all known DOM breakpoints in memory, and considers a breakpoint to be
        "resolved" once its location is pushed to the frontend.

        Breakpoints located within a child frame are still associated with the
        main frame. Whenever a the main resource of a child frame changes, all
        unresolved breakpoints associated with the main frame are speculatively
        resolved.

         - Flip leading and trailing borders and margins for the tab items.
         - Enumerate tabs in reverse order when performing manual layout.

        Flip borders that should vary in RTL vs LTR, but not all of them. In
        many cases, the border is not direction-dependent and looks the same
        on both sides. Also, no need to swap animated properties as all manual
        layout is done from the left edge.

        Web Inspector: RTL: adjust padding of dashboard icons

        Reviewed by Matt Baker.

        Extract the direction-dependent padding into a "local" variable.
        Use two rules to apply it to whichever is the leading side.

        While we tend to use leading/trailing in Apple layout technologies,
        I think the CSS logical properties specification sticks to using
        -start and -end, so let's use that nomenclature where we can.

        Web Inspector: tree elements with depth > 1 should have context menu "expand all"/"collapse all" commands
        https://bugs.webkit.org/show_bug.cgi?id=135590

        Reviewed by Timothy Hatcher.

        Rework the context menu event handlers for all TreeOutline and TreeElement instances such
        that the TreeOutline handles the event listener and creates the context menu object and the
        TreeElement populates the list with items.  This is necessary due to the way in which
        children are laid out, as there is padding on either side of the element that would not
        trigger a context menu event.

        Web Inspector: Test.html should support globals reportInternalError, reportUnhandledRejection, reportUncaughtException

        Reviewed by Joseph Pecoraro.

        We have a hodgepodge of redundant code that reports uncaught exceptions in the inspector page.
        There is better handling of uncaught exceptions in the inspected page, such as including stack traces.

        This patch consolidates a lot of this code and makes it possible to report
        unhandled promise rejections, top-level uncaught exceptions, and exceptions
        caught in a try-catch block. The formatting and sanitization code for all of
        these things is shared and consistent. Finally, some tests have been added to
        catch regressions in unhandled rejection/uncaught exception reporting.

        * UserInterface/Test/FrontendTestHarness.js:
        (FrontendTestHarness): Explicitly set initial flag state here so it's easy to find all flags.

        (FrontendTestHarness.prototype.redirectConsoleToTestOutput):
        Extract this code to sanitize stack frames and put it in TestHarness. It is used
        by other methods that need to print stack frames.

        (FrontendTestHarness.prototype.reportUnhandledRejection):
        (FrontendTestHarness.prototype.reportUncaughtException):
        Added. Sanitize stack trace data so it is deterministic. Log the message to the
        original window.console but don't exit early. Sometimes the test page is not
        fully loaded if we throw an exception quite early in the test() method, and there's
        no harm in not early returning. If we do early return in this case, then a test that
        uses reportUncaughtException on purpose may not complete because the call to completeTest()
        would be skipped by returning early.

        (FrontendTestHarness.prototype.reportUncaughtExceptionFromEvent):
        Renamed from reportUncaughtException since the signature of that method suggests
        it should have a single exception argument rather than lots of data arguments.

        * UserInterface/Test/Test.js: Add globals.

        Extract this code from other parts of the test harness. Make sanitizeStack

        'suppressStackTraces' flag.

        Web Inspector: Console could be made useful for very simple await expressions
        https://bugs.webkit.org/show_bug.cgi?id=165681
        <rdar://problem/29755339>

        Reviewed by Brian Burg.

        Normally await expressions are only allowed inside of async functions.
        They make dealing with async operations easy, but can't be used directly
        in Web Inspector's console without making your own async function wrapper.

        This change allows simple await expressions to be run in the console.
        The supported syntaxes are (simple expression with optional assignment):

            await <expr>
            x = await <expr>
            let x = await <expr>

        Web Inspector's console will automatically wrap this in an async
        function and report the resulting value or exception. For instance
        in the last example above:

            let x;
            (async function() {
                try {
                    x = await <expr>;
                    console.info("%o", x);
                } catch (e) {
                    console.error(e);
                }
            })();
            undefined

        This way users can get the convenience of await in the Console.
        This also gives users a nice way of extracting a value out of
        a Promise without writing their own handlers.

          - Sort unnamed properties by their class name (guaranteed)
          - Sort any tied class names by their object id

        This makes using the Object Graph with Name sort easier to follow.

        Web Inspector: SourceCodeTextEditor should display execution lines for background threads
        https://bugs.webkit.org/show_bug.cgi?id=164679

        Reviewed by Timothy Hatcher.

        There may be multiple threads paused in the same content view. With
        this change we should a thread indicator for each primary line a
        thread is paused on. It uses the same inline line indicator that
        inline errors/warnings (issues) use.

        When there is a single thread (just the Page) we don't show thread
        indicators. But as soon as there are multiple threads we start
        managing and showing them. The line indicator contains the name of
        the thread on the side.

        Note that SourceCodeTextEditor maintains the thread indicators, but
        it still always handles the ActiveCallFrame as it used to, pushing
        values down into TextEditor. The ActiveCallFrame styles override
        the thread line indicators (albeit with the same styles). The reason
        these are still separate is that TextEditor has some special styles
        regarding its gutter for the active execution line. Eventually we
        may want to find a way to push this up into SourceCodeTextEditor.

        Web Inspector: Worker debugging should pause all targets and view call frames in all targets
        https://bugs.webkit.org/show_bug.cgi?id=164305
        <rdar://problem/29056192>

        Reviewed by Timothy Hatcher.

        This implements a policy where, when one Target ("Thread") pauses
        the frontend triggers a pause in all other Targets. The intended
        user experience is "all threads pause" whenever the frontend shows
        the debugger paused UI.

        DebuggerManager has a few straight forward changes:

            - The paused state reflects if any target is paused.
            - The Paused Event is fired when going from !paused -> paused.
              This means when the first target pauses.
            - The Resumed Event is fired when going from paused -> !paused.
              This means only after all targets have resumed.
            - The CallFrameDidChange Event now includes the Target that updated.

        When a Target first pauses the frontend then immediately pauses all
        other Targets. This puts them into a "pausing" state (we display as
        Idle) and they will pause as soon as they start executing JavaScript.

        When a Target steps the "paused" state isn't changing. So this is
        just a CallFramesDidChange update.

        When clicking Resume we resume all targets. This is will be the normal,
        expected way users resume execution. Note that one of the threads may
        then hit a breakpoint and re-pause all threads.

        Sometimes when multiple threads are paused you may want to run an
        individual thread to completion but keep other threads paused. There
        is a context menu on the ThreadTreeElement to resume just that
        single thread. It will continue and pause for its next run loop.

        The DebuggerSidebar still has a single "Call Stacks" section, but maintains
        two TreeOutlines and only shows one at a time. The Single Thread view shows
        a flat list of the call frames for the Main Target when it is the only target.
        The Multiple Threads view shows a list of Threads and their call frames.
        We always keep both up to date, because we may need to swap between them
        purely as Targets are added / removed. There is a bit of extra logic to
        ensure we select elements properly based only on the visible tree outline.

        Web Inspector: Associate Worker Resources with the Worker and not the Page
        https://bugs.webkit.org/show_bug.cgi?id=164342
        <rdar://problem/29075775>

        Reviewed by Timothy Hatcher.

        A Target may have its own list of Resource. For example, Workers may
        request any resources via XHR/Fetch. So we associate a ResourceCollection
        with a Target, and ensure we show them in Web Inspector as you would expect.
        At this point, Target starts acting like Frame. Target has a resourceCollection
        and extraScriptsCollection just like Frame. Target has events for ResourceAdded
        just like Frame.

        Even though Resource loads are happening in Workers, the Network data
        still comes from the Page's Network agent. The added "targetId" data
        with the Resource will let us associate a Resoure with a Target.

        When opening inspector after a page has loaded, the frontend loads Resources
        via the Page.getResourceTree path. In this case, the frontend may be
        informed of Resources for a Target that it does not know about yet. In
        these cases, it sets them aside as Orphaned resources for a target. Later,
        when that Target is created, it will adopt its Orphaned resources.

        Places that used to listen to just Frame.Event.ResourceWasAdded should now
        also listen for Target.Event.ResourceAdded to ensure it sees the resources
        associated with non-page targets.

        Web Inspector: Include DebuggerAgent in Workers - see, pause, and step through scripts
        https://bugs.webkit.org/show_bug.cgi?id=164136
        <rdar://problem/29028462>

        Reviewed by Brian Burg.
        
        By implementing DebuggerAgent, Workers will inform the frontend about
        Scripts that evaluate in the Worker's VM and the Worker VM can pause
        and send the pausing CallFrames to the frontend. This means that
        WebInspector.Script and WebInspector.CallFrame will need to be made
        target aware. This also means that each Target will have its own
        set of debugger data, such as the list of scripts and pause data
        like the pause reason / call frames. Previously all this data was
        managed by DebuggerManager.

        With this change we split that data out of DebuggerManager to be
        per-target DebuggerData. DebuggerManager keeps `activeCallFrame`
        but the list of scripts and pause data have moved into `DebuggerData`
        which is per-target, accessed through DebuggerManager's new
        dataForTarget(target) method.

        Finally we make a few changes to the UserInterface to make Workers
        and their scripts, appear grouped together. The Resources sidebar
        previously had a single top level item for the Main Frame, which
        has all its resources as its children (potentially grouped into
        folders). With this change, each Worker gets its own top level
        item as well, and the Worker's subresources (imported scripts)
        become its children.

        We also now associate a single mainResource with Targets. In the
        case of Workers, we assume and assert that this is a Script. If
        this were to ever change we would need to adjust the assumptions.

        targets as other agents are implemented in workers. For example profile
        data that assumes the main target right now could be worker targets
        when we implement ScriptProfiler / Heap agents.

        the first one that matches, whose title is then applied to the input element.

        Fixed CodeMirror.undo() logic rolled out by r191539 <https://webkit.org/b/150537>

        Added calls to CodeMirror.changeGeneration(true) which tells the history stack to "close"
        the current event, preventing it from being consolidated with new changes.  If the user
        typed fast enough, non-completion changes (like adding ":" in CSS) would get merged with
        completion changes, causing calls to CodeMirror.undo() to undo those changes as well.  To
        prevent this, a boolean variable is set to true whenever a completion "activity" is in
        progress, defined by a sequence of completion related events.  When this "activity" first
        starts, call CodeMirror.changeGeneration(true) to freeze the current history.

        Web Inspector: Include RuntimeAgent in Workers - evaluate in Worker context
        https://bugs.webkit.org/show_bug.cgi?id=163835
        <rdar://problem/28901465>

        Reviewed by Brian Burg.

        This introduces the idea that the frontend may communication with multiple
        backend "Targets" which each have their own set of Agents.

            - WebInspector.Target
              - has its own list of Agents
              - has a InspectorBackend.Connection to communicate with the backend

            - WebInspector.mainTarget
              - always exists and represents the thing we are debugging (Page or JSContext)

            - WebInspector.targets / WebInspector.targetManager
              - management of all Targets
              - create new Targets for Workers

        This also slowly introduces the concept that Model objects may be tied to
        a specific Target:

            - WebInspector.RemoteObject
              - in order to evaluate JS and interact with this object we must know the target (Page or Worker)
              - when fetching PropertyDescriptors and other RemoteObjects we must continue to pass on the target

        Finally this makes the QuickConsole list Worker execution contexts in
        the context picker so that users can choose a Worker context and
        evaluate JavaScript in that context using the console.

        (InspectorBackend.Agent.prototype.get connection):
        (InspectorBackend.Agent.prototype.set connection):
        (InspectorBackend.Agent.prototype.get dispatcher):
        We will share Agent implementations but just give new "copies" a different
        connection and dispatcher.

        (InspectorBackend.Command):
        (InspectorBackend.Command.create):
        (InspectorBackend.Command.prototype.invoke):
        (InspectorBackend.Command.prototype.supports):
        We continue to have a single Command instance on the Agent. However instead
        of using the hardcoded Agent on the Instance when evaluated as a function
        it uses the `this` object which should be an agent. This way:

            target1.RuntimeAgent.evaluate
                - `this` is target1 and we use the connection for that target
            target2.RuntimeAgent.evaluate
                - `this` is target2 and we use the connection for that target

        Unfortunately this breaks `RuntimeAgent.evaluate.invoke`. Currently this
        is solved by providing an extra parameter. In the case where we need to
        invoke on a particular agent we must provide the agent.

            target.RuntimeAgent.evaluate.invoke({options}, target.RuntimeAgent)

        This is unfortunate but only needed in a handful of places right now.

        (InspectorBackend.Connection.prototype._flushPendingScripts):
        This extracts the Connection details into its own class.
        Although we make it appear as though a Target has a list of
        Agents, we actually have the Connection hold the list of Agents.
        Instead of cloning the entire Agent we just create a new object
        extended from the original Agent instance. This allows us to keep
        the same interface but just change the connection / dispatcher
        properties within the Agent.
