Evan Shrubsole 6cd6d8ecfd Introduce Sync-Decoding based on Metronome ... Adds new class DecodeSynchronizer that will coalesce the decoding of received streams on the metronome. This feature is experimental and is backed by a field trial WebRTC-FrameBuffer3. This experiment now has 3 arms to it, "WebRTC-FrameBuffer3/arm:FrameBuffer2/": Default, uses old frame buffer. "WebRTC-FrameBuffer3/arm:FrameBuffer3/": Uses new frame buffer. "WebRTC-FrameBuffer3/arm:SyncDecoding/": Uses new frame buffer with frame scheduled on the metronome. The SyncDecoding arm will not work until it is wired up in the follow-up CL. This change also makes the following modifications, * Adds FakeMetronome utilities for tests using a metronome. * Makes FrameDecodeScheduler an interface. The default implementation is TaskQueueFrameDecodeScheduler. * FrameDecodeScheduler now has a Stop() method, which must be called before destruction.
