        When the VTDecompressionSession decodes incoming H.264/H.265 samples,
        it puts guessed color space attachments on the CVPixelBuffer, and the
        guesses are based on video resolution. WebRTC streams however default
        to being sRGB. So this patch overrides a guess with what we know the
        stream will be. (Once we support different color spaces in WebRTC
        video streams we'll need to adjust this.)

        [GLIB] REGRESSION(r278701): numerous WebRTC tests failing after libwebrtc update to M92
        https://bugs.webkit.org/show_bug.cgi?id=227172

        Reviewed by Adrian Perez de Castro.

        Non-apple ports do not use the bundled libvpx library, they rely on the host libvpx instead.
        LibWebRTC expects to depend on the bundled version, thus using its API. So we need to be
        very careful with which libvpx version is used from the host, in order to avoid API/ABI
        issues. Hence the version check should specify a version that is API/ABI compatible with
        what libwebrtc expects.

        This patch also re-enables data channel support, which was disabled during the update to M92
        in CMake ports.

        Use tighter bitrate allocation rules for WebRTC H264 software encoder
        https://bugs.webkit.org/show_bug.cgi?id=226319
        <rdar://73150695>

        Reviewed by Eric Carlson.

        Software H264 encoder is sometimes overshooting target bitrate in which case WebRTC backend will start dropping frames.
        The encoder might then think it is on target and will not try to increase compression.
        This makes it possible to be locked in a very low frame rate but high quality image situation.
        It is often better to preserve frame rate and lower quality, the application could always lower frame rate if desired.

        To do so, we detect whether the encoder is using software code path or not.
        If so, we compute the actual frame rate and compare it with the expected frame rate.
        If the actual frame rate is twice smaller or even below, we enter in a low frame rate mode.
        Otherwise, we are in a regular frame rate mode where we apply the normal bitrate rules.
        In the low frame rate mode, we divide the target bitrate by 3 so as to quickly recover frame rate.

        This works well in situations where motion increases from time to time.
        It is still not perfect for instance in case the video is muted and gets unmuted or when the scene is completely still and suddenly large motion happens.
        In those cases, frame rate is recovered after a minute or so according my testing.

        CRASH in MergeUVRow_AVX2
        https://bugs.webkit.org/show_bug.cgi?id=222996
        <rdar://75183835>

        Reviewed by Geoff Garen.

        Crash logging shows occasional crashes in MergeUVRow_AVX2. These crashes  all occur when
        calling -[AVAssetImageGenerator copyCGImageAtTime:actualTime:error:]. This path is only used
        when there was no prior image generated, and a new image is not available from
        AVPlayerItemVideoOutput, which is a scenario which only occurs when doing a software-paint
        immedately after a <video> element begins loading. While we should probably stop using
        AVAssetImageGenerator, that would be a much riskier change, and wouldn't address the
        underlying cause of the crash. Instead, bailing out early when in this state would cause
        decoding to fail, but since this scenario only appears to occur for the
        AVAssetImageGenerator path, painting would quickly recover as soon as
        AVPlayerItemVideoOutput begins emitting frames.

        The explanation for these crashes seems to be a mismatch between the size of the libvpx
        output frame and the size of the CVPixelBuffer where the converted frame data is being
        stored. Add a pre-flight check that will bail out early in this scenario.

        Reviewed by Darin Adler.

        Remove support for building the debug variant since it is
        currently unused. We now set default values for the
        DEAD_CODE_STRIPPING, DEBUG_DEFINES, GCC_OPTIMIZATION_LEVEL and
        STRIP_INSTALLED_PRODUCT variables.

        Also move these values out of the Xcode project into
        Base.xcconfig files using the [config=Debug] specifier so that
        these overrides are next to the definitions.

        Additional changes in behavior are noted below.

        - Add missing copyright block.
        - Set up DEBUG_DEFINES and GCC_OPTIMIZATION_LEVEL the same as

        * Configurations/DebugRelease.xcconfig:
        - Add missing copyright block.
        - Move DEBUG_DEFINES and GCC_OPTIMIZATION_LEVEL to Base.xcconfig
          for [config=Debug].

        * Configurations/libwebrtc.xcconfig:
        - Add missing copyright block.
        - Set up STRIP_INSTALLED_PRODUCT the same as for other WebKit

        Reviewed by Darin Adler.

        Bug 42796 introduced MACOSX_DEPLOYMENT_TARGET_<PLATFORM> as "support
        for compiling WebKit against iOS SDKs". Support for the iOS part of
        this feature was later removed in several changes, including Bug
        139212, Bug 139463 and Bug 144762. However, vestiges have remained for
        five or six years in the form of MACOSX_DEPLOYMENT_TARGET_macosx. The
        inclusion of the platform in MACOSX_DEPLOYMENT_TARGET is no longer
        needed and can be removed.

        This changes brings most projects in conformance with other projects
        that don't support including the platform in MACOSX_DEPLOYMENT_TARGET,
        including WebEditingTester, gtest, WebKitTestRunner, MiniBrowser, and
        TestWebKitAPI.

        Along the way, remove a couple of left-over references to macOS 10.16,
        and a couple of places where [sdk=macosx*] was still being used.

        With this change, initialization of MACOSX_DEPLOYMENT_TARGET should be
        consistent across all projects, with two exceptions: WebKitLauncher
        (which hardcodes it to 10.12) and libwebrtc's copy of googletest
        (which hardcodes it to 10.4). The reasons for these hard-coded values
        is not apparent, so leave them be.

        Due to a bug in Xcode (rdar://70185899), Xcode 12.0 and Xcode 12.1 Beta incorrectly includes the 
        minor release number in MAC_OS_X_VERSION_MAJOR, which causes Debug and Release builds of WebKit 
        to be misconfigured when building on macOS Big Sur SUs, leading to webpages failing to load.

        To work around the Xcode bug, when the MAC_OS_X_VERSION_MAJOR includes the minor version number, 
        drop the minor version number by explicitly setting TARGET_MAC_OS_X_VERSION_MAJOR to 110000.

        <rdar://problem/69992230>

        Reviewed by Darin Adler.

        Under XCBuild, the scripts employed in custom build rules can be
        invoked in innocuous situations. A common example is when the user is
        building from the command-line and they change the `make` output from
        stdout to a file, or vice-versa. Changing the output changes the
        setting of the COLOR_DIAGNOSTICS environment variable, which is enough
        to cause XCBuild to think something is different and that the custom
        build rule needs to be invoked. For the script's part, nothing
        significant has changed, yet it post-processes the header files,
        causing their modification dates to change, causing downstream
        rebuilds to occur.

        Fix this problem by adopting an approach that doesn't modify the
        post-processed header files unless their contents actually change.

        Add the vp9_header_parser from libwebrtc to the project, and add its
        symbols to the list of exported symbols. Because this header wants to
        be installed to a "common/vp9_header_parser.h" path, split up the default
        CopyHeadersInstallPhase into two separate CopyFiles build phases that
        put headers into different locations.

        Update WebKit binding code to switch on/off VP9 encoder/decoder.
        We still use vp9_noop for now, so encoder/decoder is not functional.

        Reviewed by Eric Carlson.

        Add logging for encoded frames taking a long time to be received.
        We log the time take to receive the frame, the time since previous frame, the byte size of the frame.
        We compute that a frame takes too long by checking whether it is delayed by more than three expected frames.

        Enable the use of XCBuild by default in Apple builds
        https://bugs.webkit.org/show_bug.cgi?id=209890
        <rdar://problem/44182078>

        Reviewed by Darin Adler.

        Switch from the "legacy" Xcode build system to the "new" build system
        (also known as "XCBuild"). Switching to the new system speeds up
        builds by a small percentage, better validates projects for
        build-related issues (such as dependency cycles), lets WebKit benefit
        from future improvements in XCBuild such as those coming from the
        underlying llbuild open source project, and prepares us for any other
        tools built for this new ecosystem.

        Specific changes:

        - Remove Xcode project and workspace settings that selected the Build
          system, allowing the default to take hold (which is currently the
          New build system).
        - Updated webkitdirs.pm with a terser check for Xcode version.
        - Update build-webkit and Makefile.shared to be explicit when using
          the old build system (no longer treat it as a default or fall-back
          configuration).
        - Update various xcconfig files similarly to treat the default as
          using the new build system.
        - Update various post-processing build steps to check for Xcode 11.4
          and to no longer treat the default as using the old build system.

        I believe this was done by accident in a larger patch. If we did indeed
        want to define OTHER_CFLAGS to be empty, the right place for that is inside
        the xcconfig files, not the pbxproj files.

        <rdar://problem/61502270>

        Reviewed by Jonathan Bedard.

        When building with the public version of Xcode 11.4, with XCBuild
        enabled, and targeting the iOS device, some build targets issue an
        error like:

            error: An empty identity is not valid when signing a binary for
                the product type 'Command-line Tool'. (in target 'yasm' from
                project 'libwebrtc')

        A comment in <rdar://problem/47092353> suggests setting
        ENTITLEMENTS_REQUIRED=NO to relax the requirement. To that end, when
        building with the public Xcode, establish that setting for the
        affected targets.

        This can be avoided by default-initializing the
        FrameGeneratorCapturerConfig::ImageSlides::Crop member variable instead
        of specific members of that class.

        Similar fix will be pushed to the upstream repository.

        Reviewed by Daniel Bates.

        Enable building with Thin LTO in Production when using Xcode 10.2 or
        later. This change results in a 1.45% progression in PLT5. Full
        Production build times increase about 2-3%. Incremental build times
        are more severely affected, and so LTO is not enabled for local
        engineering builds.

        LTO is enabled only on macOS for now, until rdar://problem/49013399,
        which affects ARM builds, is fixed.

        To change the LTO setting when building locally:

        - If building with `make`, specify WK_LTO_MODE={none,thin,full} on the
          command line.
        - If building with `build-webkit`, specify --lto-mode={none,thin,full}
          on the command line.
        - If building with `build-root`, specify --lto={none,thin,full} on the
          command line.
        - If building with Xcode, create a LocalOverrides.xcconfig file at the
          top level of your repository directory (if needed) and define
          WK_LTO_MODE to full, thin, or none.

        XCBuild changes the way xcconfig variables are evaluated. In short,
        all config file assignments are now considered in part of the
        evaluation. When using the new build system and an .xcconfig file
        contains multiple assignments of the same build setting:

        - Later assignments using $(inherited) will inherit from earlier
          assignments in the xcconfig file.
        - Later assignments not using $(inherited) will take precedence over
          earlier assignments. An assignment to a more general setting will
          mask an earlier assignment to a less general setting. For example,
          an assignment without a condition ('FOO = bar') will completely mask
          an earlier assignment with a condition ('FOO[sdk=macos*] = quux').

        This affects some of our .xcconfig files, in that sometimes platform-
        or sdk-specific definitions appear before the general definitions.
        Under the new evaluations rules, the general definitions alway take
        effect because they always overwrite the more-specific definitions. The
        solution is to swap the order, so that the general definitions are
        established first, and then conditionally overwritten by the
        more-specific definitions.

        [GTK][WPE] Remove gflags from libwebrtc build
        https://bugs.webkit.org/show_bug.cgi?id=187078

        Reviewed by Alejandro G. Castro.

        gflags is used only in libyuv unit tests. So the Apple ports do not build & link it.
        GTK and WPE can do the same thing: not building gflags. By doing so, we can achieve
        the following results.

        1. Remove static initializers defined for gflags.
        2. Reduce binary size.

        Reviewed by Youenn Fablet.

        There are a number of files in webrtc that have main() functions (in
        particular, rtpcat.cc and click_annotate.cc). When compiling with LTO,
        these symbols are exposed to each other, leading to the following
        build failure:

            Ld libwebrtc.dylib
            duplicate symbol _main in:

        Use libwebrtc ObjectiveC H264 encoder and decoder
        https://bugs.webkit.org/show_bug.cgi?id=183912

        Reviewed by Eric Carlson.

        Add utilities inside libwebrtc to be used by WebKit:
        - Create ObjectiveC encoder/decoder factories
        - Notify of application status to invalidate encoders/decoders when in background
        Implement RTCUIApplicationStatusObserver as a simple boolean that is set by WebCore.
        This allows limiting the changes made to libwebrtc codec implementations.

        Minor modifications done to libwebrtc to fix compilation.
        Add Block_copy/Block_release to codec callbacks.

        Below files have been modified to adapt for WebKit.
        Patches for various parts are kept in WebKit folder.
        In addition to these changes, VTB codecs and factories used by WebKit
        are now added inside libwebrtc in webrtc/sdk/WebKit.
        Future refactoring should consolidate these files.

        https://bugs.webkit.org/show_bug.cgi?id=173223

        Reviewed by Sam Weinig.

        The rebuilds were happening due to a difference in the compiler options that the IDE and
        xcodebuild were specifying. Only the IDE was passing the -index-store-path option. To make
        xcodebuild pass that option, too, set CLANG_INDEX_STORE_ENABLE to YES if it is unset, and
        specify an appropriate path in CLANG_INDEX_STORE_PATH.

        Libwebrtc network thread is set up so that it does not accept blocking calls to other threads.
        as per ChannelManager::Init() in channelmanager.cc.

        [WebRTC] Remove libwebrtc ObjectiveC files that use UIKit
        https://bugs.webkit.org/show_bug.cgi?id=168392

        Reviewed by Alex Christensen.

        Removing default AudioDeviceModule as WebKit is providing its own.
        Removing checks for active application in H264 codec as WebKit should be made responsible for that.
        Removing no longer needed ObjectiveC files.

        We were building libwebrtc as a static library, which would prevent us from weak linking with it.
        We need to explicitly export what we use from WebCore or WebKit2, and RTCLogging.mm now needs to
        be built on Mac, so we make it not automatically reference counted to make it work on 32-bit El Capitan.
