This first of all does some refactoring of how metadata is encoded in
MediaEncoder. This is now guided by the new Muxer class. If we're ready to pass
data to the muxer and it does not have metadata yet, we provide metadata before
giving it any media data. This metadata is passed to the muxer in a single call.
The metadata provided in this call must stay valid for the entire recording.
This removes MediaEncoder::GetEncodedMetadata().
This also removes the ctor argument from the WebMWriter since it can now rely on
the single SetMetadata() instead.
To comply with the ContainerWriter::SetMetadata() docs,
WebMWriter::SetMetadata() will now also sanity check metadata.
ContainerWriter instances are updated somewhat, to accommodate these changes.
Lastly, and most important, the new Muxer class manages muxing of the (up to)
two tracks into a single container, ensuring that timestamps increase
monotonically throughout a recording.

This is inherently large, because modifying these bits of DOMMediaStream and
MediaStreamTrack affects all consumers and producers of all DOMMediaStreams and
MediaStreamTracks.
Things are generally much simpler now.
Producers of tracks now create a MediaStream in the graph, add it to a
MediaStreamTrackSource subclass that takes ownership of it, and add the source
to a MediaStreamTrack. Should the producer need a DOMMediaStream it is now much
simpler to create as the only thing needed is the current window. The stream is
a rather simple wrapper around an array of MediaStreamTracks.
HTMLMediaElement is still not as straight forward as other consumers since it
consumes the DOMMediaStream directly, as opposed to a set of tracks.
The new MediaStreamRenderer helper class helps bridge the gap between this fact
and the new track-based MediaStreamGraph interface, as it needs to juggle
registering multiple audio tracks for audio output. This hooks into existing
HTMLMediaElement logic and brings a welcome simplification to all the glue
previously needed there.

Somewhere along the way this must have gotten broken.
Until this, passing mime type to MediaRecorder has had no effect.
This patch does two things:
1) Passes the mime type through from MediaRecorder to MediaEncoder
2) Gives preference to the mime type when passed, wrt picking codecs,
however, we still yield to a video mime type when given a video track
since that's how both Firefox and Chromium function today.
Proper spec handling of mime type will be fixed in bug 1512175.

These are added in start, and we get into unexpected state if they notify us
after Stop() (when MediaEncoder shuts down and internally removes the tracks
it is encoding) but before Shutdown() when we remove the listeners. This is not
symmetrical. The proper thing to do is to remove these listeners in Stop() as
well.

Because we sync video frames to audio time before encoding, we suspend and
resume on the audio thread because that's the only place we have acccess to
both clocks at the same time;
- A dispatch to the audio encoder puts the event in the right place in the
audio encoder buffer.
- TimeStamp::Now() is the current video time, and since we capture it on the
audio thread these are in sync. This timestamp needs drift compensation too -
this happens in a later patch on this bug.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
