The VideoSink shares the AudioSink's own EndedPromise to notify its user that it has ended. As such, the MozPromise used must be non-exclusive.
Using the GenericPromise for such purpose only hid that requirement.
We also remove the MediaSink from the media namespace, and clarify the naming of some arguments and class members to accurately describe what they do.

This removes DecodedStream's use of MediaStreamListener in favor of
MediaStreamTrackListener. This change has however rippled through to a lot
more cleanup, per below.
This moves the MediaStreamTrack lifetime ownership for captured
HTMLMediaElements from the media element to DecodedStream, where the
MediaStreamGraph-side tracks are already created and ended today.
This makes MediaStreamTrack creation explicit across the entire codebase and
lets us remove the MediaStreamTrackSourceGetter class and the infrastructure
of adding MediaStreamTracks after they've already been created in the graph
from DOMMediaStream.
With track ownership, and thus TrackID allocation ownership, happening
exclusively in DecodedStream for its output tracks, we also stop throwing
away and recreating the SourceMediaStream to which we feed data on seek.
This is one step closer to fixing bug 1172394 and spec compliance of
HTMLMediaElement.captureStream().

This patch converts all the prefs in MediaPrefs to the new StaticPrefs system.
Note that the "media.wmf.skip-blacklist" pref was present in both MediaPrefs
and gfxPrefs. The copy in MediaPrefs was never used; this explains why this
patch does not add an entry for it to StaticPrefList.h.
Note also that the patch removes themedia.rust.mp4parser pref, because it's
unused.

We have code in the MDSM to toggle on high resolution timers on Windows when we
start/stop playing because the VideoSink relies on being awoken by timers to
update the set of current frames in the compositor's queue, and on Windows 7 we
end up dropping frames due to the timer lag without this.
We assert in the MDSM's destructor that we've turned off high res timers (as
they cause needless battery drain, so we only want them on when we need them),
and the new test_mediarecorder_principals is hitting that assert on Windows. I
think we're missing turning them off when we create a new VideoSink for
outputting to the MSG. That affects the value returned by
MediaDecoderStateMachine->mVideoSink->IsPlaying(), which is what we use to
decide whether we should enable high resolution timers. We track whether we've
enabled high res timers in MDSM::mHiResTimersRequested, and that gets out of
sync with IsPlaying() when we re-create the MediaSink.
Rather than trying to handle all the permutations of places where we need to
turn off high resolution timers in the MDSM, we're better to move the code to
toggle high res timers into the VideoSink, as that's actually where we need to
be sure that we have high resolution timers enabled anyway. It's the VideoSink
after all that is relying on timers for frame update, not the MDSM.
Also remove the media.hi-res-timers.enabled pref, as we haven't needed it.

Channel layout is derived by the content being played. The concept of preferred layout is meaningless. Either we have a layout defined, or we don't. There's no in-between.
