This patch takes a stab at modules/video_coding,
but reaches only about half.

f7a1937e70 Add FrameBufferProxy test for low-latency renderer
Ensures that frames are decoded instantly when in low-latency render
mode. This also tests the max queue size behaviour. Adds a new test
suite for FrameBufferProxy that sets the appropriate field trials.

* Fixes FrameDecodeTiming to never use negative wait times for decode
timestamps.

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.

9a99905301 Implement FrameBuffer3Proxy
This emulates behaviour from frame buffer 2, but does not handle stats.
In contrast to frame buffer 2, all work happens on the same task queue.
FrameBuffer3Proxy encapsulates FrameBuffer3 and scheduler behind
a field trial WebRTC-FrameBuffer3.

This separates frame scheduling behaviour into a few components,

VideoReceiveStreamTimeoutTracker
* Handles the stream timeouts.

FrameDecodeScheduler
* Manages the scheduling and cancelling of frames being sent to the
  decoder.

FrameDecodeTiming
* Handles the timing and ordering of frames to be decoded.

Other changes
* Adds CurrentSize() method to FrameBuffer3
* Move timing to a separate library
* Does a thread check for Receive statistics as this is now
on the worker thread.
* Adds `FlushImmediate` method to RunLoop so that
  video_receive_stream2_unittest can pass when scheduling is happening
  on the worker thread.

9d29026216 Add FrameBufferProxy in prep for FrameBuffer3
This is a delegate that is used by video_receive_stream2 to handle frame
buffer tasks like threading, and stats. This will be used in a follow up
to use FrameBuffer3 as a strategy selected by field trial.

Unit-tests will be used in follow-up CLs containing Frame Buffer 3, and
are expected to work with both Frame buffer proxy versions.
