We had problems because we'd call Destroy on a port after calling Destroy on
its streams. This patch makes the port's Destroy ControlMessage not use a stream,
instead we get the stream from the port directly. It also makes us update the
graph's mPortCount only when the port is finally destroyed; this fixes a potential
bug where the current graph could shut down when all streams are removed, before
all ports have been completely destroyed.

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.
