test_streams_element_capture_reset.html is updated to test that mozCaptureStreamUntilEnded actually stops
capturing when the stream ends. It also tests that seeking and reloading the media resource keep
feeding a mozCaptureStream stream, and feed the right amount of data.

Moves to a new setup where a decoder manages a single SourceMediaStream internally. Each stream
returned from mozCaptureStream(UntilEnded) is a TrackUnionStream which is fed by the
decoder's SourceMediaStream.
We want the captured streams to be blocked while the media element is not playing. We do that
by blocking any captured stream that has no SourceMediaStream feeding into it, and blocking
any SourceMediaStream while its decoder is not playing.
We arrange for the decoders's PlaybackEnded to be delayed until its SourceMediaStream has
finished according to the media stream graph. This ensures the state of captured media streams
corresponds more closely to the media element state.

Until now we've identified the "first active track" of a stream and played only that. Instead,
it makes more sense to play all the tracks.
For video, we pick the last track that has a video frame for the current time, and display that.

The main thing this patch does is to add ProcessedMediaStream objects and
MediaInputPorts connecting streams. ProcessedMediaStreams are an abstract
class that doesn't constrain what processing is actually performed, except
that for now we assume a stream's processing depends only on its inputs
window of data between mCurrentTime and mStateComputedTime.
This patch reorganizes the way the blocking status of each stream is computed.
The streams are partitioned into groups so that every stream which can affect
the blocking status of another stream is in the same group as that other stream.
We also add a pass to order the streams by dependency so we can process the streams
in order of dependency; this pass also identifies the streams that form part of a
cycle.

The Opus audio format supports multichannel (surround) audio, but our initial implementation used a simpler API which only supported mono and stereo output.
To handle these files gracefully, this patch uses the multichannel api and downmixes the output, if possible, to stereo, since we don't currently support surround sound playback.
This is actually a better fix for bug 774597. We can rely on main thread code to call
Destroy on all the MediaStreams normally. These Destroy calls can be handled even when the
MediaGraph thread has been shut down, since MediaStreamGraphImpl::AppendMessage will
call RunDuringShutdown on the Destroy messages.
Rename mBlockingDecisionsMadeUntilTime to mStateComputedTime. The invariant is that
all graph state is known up to mStateComputedTime but not beyond it (except for some
stream contents that may be buffered beyond it).
Get rid of mMessageAffectedTime and all the code around computing "affected times" and "action times".
Instead, all messages take effect at mStateComputedTime.
Get rid of the two-phase execution of messages. Everything can just happen in a single Run() method.
