Forward the number of skipped frames by the OS in audio playout.
* Introduce AudioOutputBufferParameters in media/audio/audio_parameters.h. This contains number of skipped frames.
* Change the shared memory to hold AudioOutputBufferParameters before the audio data.
* Forward skipped frames by OS on Mac over IPC. Not yet used by any client.
This relands https://codereview.chromium.org/1487983002/ which was reverted due to crackling flash (pepper) audio.
Original CL is in patch set 1.
Will be done in follow-up CLs:
* Forward skipped frames by OS on Windows.
* Forward skipped frames to the WebRTC AEC.
BUG=560371
