New issue 16508 by [email protected]: Implement a proper clock for the  
media pipeline
http://code.google.com/p/chromium/issues/detail?id=16508

Currently we base our clock on the audio hardware.

This introduces issues when hardware isn't present or when playing a video
without an audio track.

For starters, the clock logic should be extracted from the pipeline and
moved into a separate interface + implementation.  Clocks should also be
injected into the pipeline for testing/mocking purposes.

In essence, the clock should use the system time as a basis for all time-
related calculations, as opposed to being manually updated when the audio
hardware responds.

The end result should be that videos without audio should play at nearly
the same rate as videos with audio that are clocked to the hardware.
