In test_getUserMedia_audioCapture, the track of the OscillatorNode being

ended notification on the node's track but its pipe track. Recording via

MediaRecorder listens to this track directly because it has

This change mainly removes the `mTracks` member from MediaStream and moves all
associated members up a level, so that a MediaStream in practice represents a
single track.
Classes will be renamed in a future patch to reflect this.
Other changes include:
The new `mEnded` member of MediaStream changes meaning to only become true when
all data in the stream has been processed. It stems from
StreamTracks::Track::mEnded which used to become true as soon as the last bit of
data had been added to a track, and there could still be data in the track that
would get processed in future iterations. We are moving towards not having any
future data in tracks, which is why this change is ok to make -- keeping the old
behavior will soon not make sense.
TrackUnionStream is changed to no longer take a list of streams as input and
forward the union of their tracks to itself. Instead it's limited to having one
track as input at a time.
The autofinishing functionality that TrackUnionStream had before has been
transformed into an autoending functionality to allow it to defer ending until
its been told that it's ok to end through the control API. This lets a single
TrackUnionStream span the lifetime of multiple inputs, which will be useful for
making DecodedStream spec compliant with HTMLMediaElement::CaptureStream(), and
for implementing the currently discussed MediaRecorder::ReplaceTrack(), to name
a few potential use cases.
AudioNodeStreams used to only have a track (and thus an AudioSegment) if the
EXTERNAL_OUTPUT flag was enabled on them. With all MediaStreams now representing

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.

and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

Direct use of aInput buffers for ArrayBuffer elements is not possible in
general. aInput buffers are const because they may be used elsewhere but
ArrayBuffer elements may be modified by script. If necessary, it would be
possible to later add a mechanism to mix inputs directly into the ArrayBuffer,
but often no mixing is required.
Direct use of output ArrayBuffer elements would require DetachArrayBuffer to
ensure the elements are not modified by script, but that would require
creation of a new ArrayBuffer JS object on each call.
https://github.com/WebAudio/web-audio-api/issues/1932 tracks specification of
making output data available for reading (for downstream node input).

It is easier to make a span than an nsTArray.
This also clarifies that the output array lengths are not modified.

When Firefox is configured to resist fingerprinting, the latency figure returned
is the most commonly found on a particular OS.
For Android, I got data from [0], roughly copy/pasted the table into a file and
did:
```
cat file | cut -d $'\t' -f4 | grep "^[[:digit:]]" | cut -d ' ' -f 1 | sort -h
| uniq -c | sort -h
```
which indicated that 40ms was a good number for round trip latency (input to
output). Since this is for output latency only and the audio path
is roughly symmetrical in terms of duration, we report 20ms.
For OSX, 512 is always used with the default hardware in Firefox, with this
patch, it's always 512 regardless of the setup.
On Linux/Pulse, we use 25ms [1] always, and this is adjusted by PulseAudio. This
makes it always return 25ms.
On Windows, there is a wide variety of configurations, but it's common to be in
the ballpark of 80ms output (this is very empirical, by testing a bunch of
hardware over the years).
For other OSes, we use 2048 frames (adjusted to the sample-rate).

This also removes the following prefs, because they're unused:
- media.autoplay.allow-muted pref
- media.autoplay.blackList-override-default
