        Adopt AVContentKeySession

        Reviewed by Eric Carlson.

        Adopt a new API for managing key state, AVContentKeySession. Because this necessitates a change
        in both the initialization data returned by the needkey event, and passed into the createSession()
        method, bump the protocol version number (to 3), and keep supporting the old key management API
        for legacy content.

        To do so, move most of the implementation of CDMPrivateMediaSourceAVFObjC into a new subclass,
        CDMSessionAVStreamSession, and add a new subclass, CDMSessionAVContentKeySession, to support the

        [css-grid] Fix height computation of grid items with borders inside fr tracks
        https://bugs.webkit.org/show_bug.cgi?id=151798

        Reviewed by Zalan Bujtas.

        Since r192154 we run a second pass of the track sizing
        algorithm whenever the height of the grid is indefinite in
        order to properly compute row sizes. The available space
        passed to the track sizing algorithm must not contain neither
        borders nor paddings, otherwise it will think that it has more
        space available than the existing one. We should use the
        height of the content box instead.

        When returning text to be displayed, an <option> element will return
        the value of a label attribute if it exists, or the text content as a
        fallback. The failing test concerned the display of a <select>
        element when it contained a sole <option> element that had a label
        attribute set to a single space. When displayed, various
        platform-specific bits of code will strip off the leading and trailing
        whitespace. However, when WebKit would use this text to measure how
        wide the <select> popup menu button should be, it would not strip off
        spaces, leading to the calculated width being wider than necessary.
        The approach taken to fix this is to strip whitespace in the label
        attribute before it is returned from the <option> element.

        No new tests. fast/forms/HTMLOptionElement_label03.html had been
        marked as being expected to fail in TestExpectations; that test now

        STL reverse_iterators are a tricky beast.
        
        They are implemented in terms of a normal forward iterator (called the "base" iterator),
        and they decrement a copy of that iterator when dereferenced.
            
        So when monitoring deletes from  a std::set to check if we should invalidate our current 
        reverse_iterator, we were incorrectly comparing the deleted key to the value pointed by the
        reverse_iterator instead of its base iterator.
        
        Since the iterators in question are bidirectional, anyways, we can just use a single iterator
        and either increment or decrement it as needed.

        When restoring the user interface when exiting PiP, we should return to Fullscreen if that

        - MicrotaskQueue now has a mainThreadQueue() static function, replacing the old singleton() function,
          which can be used for the Document (non-Worker) Microtasks. For Workers, the a MicrotaskQueue 
          can be separately allocated for each WorkerGlobalScope (though this was not done in this change).
        - Adds a helper subclass of Microtask, ActiveDOMCallbackMicrotask, for Microtasks that are

        Unify font-variant-* with font-variant shorthand
        https://bugs.webkit.org/show_bug.cgi?id=149773

        Reviewed by Darin Adler.

        This patch makes font-variant a shorthand for the following properties:
        font-variant-ligatures
        font-variant-position
        font-variant-caps
        font-variant-numeric
        font-variant-alternates
        font-variant-east-asian

        This is consistent with the CSS Fonts Level 3 spec.

        Add a setting and restriction which will pause invisible autoplaying video
        https://bugs.webkit.org/show_bug.cgi?id=151412

        Reviewed by Eric Carlson.

        Test: media/video-restricted-invisible-autoplay-not-allowed.html

        Drive-by fix: m_autoplaying is reset in many places by calling pause() or play(), where those
        calls did not originate from an explicit request to pause or play, e.g., during an interruption.
        This causes m_autoplaying to be set to false, thus breaking resumption of autoplaying when the
        interruption ends. Update PlatformMediaSession to remember its client's "autoplaying" state and
        restore it when an interruption ends.

        Add a means to register for viewport visibility notifications to FrameView, RenderView,
        and RenderElement. Elements who wish to recieve these notifications must do so through their
        renderer, and thus will have to re-register whenever a new renderer is attached.

        Add a restriction to HTMLMediaElement which will pause autoplaying video when that video scrolls
        out of the viewport, or is hidden with CSS.

        [SVG -> OTF Converter] Force UnitsPerEm to 1000
        https://bugs.webkit.org/show_bug.cgi?id=151650

        Reviewed by Antti Koivisto.

        According to the Adobe Type 1 Font Format:

        "Type 1 font programs generally use a 1000 to 1 scaling matrix
        for the definition of the relationship of character space unites
        to user space units."

        Windows actually disregards the "unitsPerEm" value in the "head"
        table for some calculations, and hardcodes 1000 instead. In order
        to have consistent renderings on Windows and OS X, this patch
        forces all generated fonts to have a unitsPerEm of 1000, and
        appropriately scales all necessary values.

        Fix anomaly where isMouseEvent returns false for wheel events
        https://bugs.webkit.org/show_bug.cgi?id=151685

        Reviewed by Alexey Proskuryakov.

        Back three years ago when we made WheelEvent inherit from MouseEvent,
        someone decided that isMouseEvent should return false for the wheel events.
        An audit of all the callers of isMouseEvent indicated that in almost every
        case, it's better to return true, so this patch does that.

        All the other call sites that were checking isMouseEvent, here and in the
        higher levels of WebKit, benefit from getting true even for wheel events.

        * bindings/objc/DOMEvents.mm:
        (kitClass): Use eventInterface instead of isMouseEvent to create the appropriate
        wrapper class.

        * bindings/scripts/CodeGeneratorJS.pm:
        (GenerateConstructorDefinition): Eliminated a peculiar search and replace
        mistake; "stateution" instead of "execution".

        * dom/Node.cpp:
        (WebCore::Node::handleLocalEvents): Add an isWheelEvent check here so that we
        will not ignore wheel events. This preserves behavior. A FIXME questions whether
        that is the behavior we want.

        * html/HTMLTextAreaElement.cpp:
        (WebCore::HTMLTextAreaElement::defaultEventHandler): Removed unneeded checks for

        [iOS] Adjacent emoji overlap each other

        Reviewed by Simon Fraser.

        This is a partial revert of r188737. It turns out that only CoreText gives correct
        glyph advances for emoji. In r188737, I reverted the special iOS emoji processing,
        but also removed the logic of using CoreText for emoji advances. This patch adds
        the m_isEmoji boolean back, so we can tell if we need to force
        platformWidthForGlyph() to use CoreText.

        This patch also performs a little bit of cleanup by moving Font's m_isSystemFont
        to FontPlatformData where it belongs.

        [Win] Web fonts with small caps have excess whitespace with the complex text codepath
        https://bugs.webkit.org/show_bug.cgi?id=151698

        Reviewed by Darin Adler.

        When performing small-caps on OS X, we bake in the smaller font size into the platform's native font
        object. On Windows, we currently don't do that; instead, we just change some ancillary data inside
        the FontPlatformData, and our advance & drawing calculations are sensitive to this ancillary data.
        However, in the complex text codepath, Uniscribe only takes the native font object as input, and
        therefore operates with the wrong font size.

        The solution is to bake the smaller font size into the native platform font on Windows, similar to
        OS X. It isn't clear why we didn't do this previously, but it seems like we weren't sure that
        Windows would select the correct font when we provide new selection criteria. However, for web fonts,
        we already use the same mechanism (CreateFontIndirect()) when we create the font in the first place;
        therefore, this scaled font request will always work as well.

        This happens when the frame notifies its observers that the page
        will be detached. The m_table that asserts is the
        FrameDestructionObserver HashSet. It happens when clearing the
        GObject DOM cache wrappers during frame destruction, and there's a
        Document object wrapped whose last reference is held by the DOM
        wrapper. In that case, the Document object is destroyed while the
        frame is being destroyed. Deleting the wrapper objects after the
        frame destruction fixes the crash.

        The cause of this issue is that the painting order is different from the hittest order so we can end up
        with visible but unreachable content. To fix this, the executation flow of hittest has been reordered.
        According to the paint system, which renders the webpage from the bottom RenderLayer to the top, contents
        are rendered before floats. Hence, for the hittest, which determines the hitted location from top RenderLayer
        to the bottom, should do it reversedly. Now, hittest will first test floats then contents.

        Split platform-independent logic in AVCaptureDeviceManager out into a new class
        https://bugs.webkit.org/show_bug.cgi?id=151388
        <rdar://problem/23593980>

        Reviewed by Eric Carlson.

        To prepare for creating a MockCaptureDeviceManager to be able to test
        MediaDevices.getUserMedia, we create a platform-independent capture device manager
        which all platforms should extend and add platform-specific logic to.

        The methods CaptureDeviceManager::createMediaSourceForCaptureDeviceWithConstraints and
        CaptureDeviceManager::captureDeviceList should be overridden by each platform
        CaptureDeviceManager to respectively create a RealtimeMediaSource and return a list of
        capture devices. createMediaSourceForCaptureDeviceWithConstraints attempts to create
        a media source for a given device with some constraints; if the contraints cannot be
        satisfied, this returns null.

        The refactored capture device manager also introduces the notion of a platform-
        independent capture session which may be extended by platform device managers for
        determining whether a given constraint name, value and media type is valid.

        A platform-independent CaptureDeviceInfo now represents either the video or audio
        component of a capture device, but not both at once. This means a capture device that
        supports both video and audio will emit two separate capture devices.

        No new tests, since there should be no behavior change.

        [Content Filtering] Crash in DocumentLoader::notifyFinished() when allowing a media document to load
        https://bugs.webkit.org/show_bug.cgi?id=151433
        rdar://problem/23506594

        Reviewed by Alexey Proskuryakov.

        When the main resource of a media document commits, WebKit cancels its load since the plug-in or media engine
        will do its own loading. If content filtering is enabled, and the filter waits allow the load until the entire
        resource is downloaded, then ContentFilter will attempt to call DocumentLoader::notifyFinished() immediately
        after delivering the buffered resource data to DocumentLoader. However, delivering the data will have nulled out
        DocumentLoader's m_mainResource when the load was cancelled, leading to a crash in notifyFinished().

        To resolve this, add a new Stopped state to ContentFilter. Set this state if DocumentLoader clears its main
        resource or detaches from its frame. If ContentFilter is in the Stopped state after calling
        DocumentLoader::dataReceived(), do not proceed to call DocumentLoader::notifyFinished().

        Reviewed by Timothy Hatcher.

        InspectorController and InspectorFrontendClient should know how to compute their
        inspection levels, so that this level can be exposed to the Inspector frontend for
        preference disambiguation by inspection level.

         - A Page with normal web content has an inspection level of 0.
         - The first Web Inspector has an inspection level of 1.
         - The second Web Inspector that inspects the Inspector has an inspection level of 2.
         - And so forth...

        For local frontend clients (WK1 and the ProtocolTestStub), the inspection level of
        a Page computed as follows:

        - If the page's inspector controller has no frontend client, then the Page
        is normal web content (level 0).
        - If the page's inspector controller has a frontend client, ask for its inspection level.
        A frontend client looks at the inspection level reported by inspected page's inspector
        controller and increments by one to account for the crossed inspection boundary.

        No new tests, this is blocked by test infrastructure fixes (https://webkit.org/b/151573).

        When in quirks mode, abnormally huge margins could lead to

        negative freeSpace values are valid (i.e. the condition is not

        Reviewed by Carlos Garcia Campos.

        platformActiveSelectionBackgroundColor(), platformInactiveSelectionBackgroundColor(), etc.
        are const functions intended only to return a color used for painting, but since r174929
        they also change the state of the cached style contexts we use for GTK_TYPE_ENTRY and
        GTK_TYPE_TREE_VIEW. That's wrong; those style contexts should not have any state set. This
        could cause theme colors returned by those GtkStyleContexts to change unexpectedly,
        depending on whether the state is explicitly set before each use, or whether the theme
        actually uses the states.

        This didn't cause any regression only because every place using these style contexts
        explicitly sets the state of the style contexts before use. In fact, the GtkTreeView style
        context is not used anywhere else, and the GtkEntry style context is only used in
        paintTextField, which does set the state before use (and then reverts it using
        save/restore), so this cannot have broken anything in practice. But it's a landmine waiting
        for the next programmer to trip it.

        Fix this with a gtk_style_context_save()/gtk_style_context_restore() pair.
