Performing all audio processing operations in the same place, allows to simplify the code.
Additionally, if accessibility.monoaudio.enable is not set, we always upmix mono to stereo so that if the first audio stream seen was mono, we aren't stuck playing all future streams in mono.

We attempt to avoid unnecessary resampling of 44.1kHz and 48kHz content, for all others we use cubeb's preferred sampling rate as final sampling rate.

The audio is automatically converted to always match the format of the first processed sample.
This is a temporary approach, as it would be preferred to use a final sampling rate not causing too much quality loss.

Using the gfxprefs for the time being, in order to access the preferences outside of the main thread.
It will allow to easily test future cubeb changes to support change of sampling rate / multichannels.

Rather than performing the audio processing a few frames at a time, we perform the operation when popping the audio data block.
The only downmixing task left to AudioStream is to handle the force mono preference.
Resampling is currently disabled.

PrincipalHandle is a thread safe pointer to a holder of (the main-thread-only
nsIPrincipal) that can be passed around the MSG.
A MediaStreamTrack whose source has just updated its principal, sets the new
principal aside (as its "pending principal"), and combines the new principal
into its current principal.
Then the source starts passing the new principal to the MediaStreamGraph as
a PrincipalHandle.
Changes to a track's PrincipalHandle on the MSG will be surfaced through the
MediaStreamTrackListener API. These changes are dispatched to main thread
and compared to a MediaStreamTrack's pending principal. In case of a match
the track knows the correct principal is flowing and can move the pending
principal to be the current principal and update any main thread principal
observers.

This is a partial reversal of bug 1230338. We can't distinguish frames that are never composited because the media element is hidden from the frames genuinely dropped due to machine slowness. So until we can distinguish them, let's not report them as dropped.

The way we pass in AudioDataValue arrays into AudioData is non-uniform:
sometimes we have nsAutoArrayPtrs, sometimes we don't, and it's not
immediately obvious from the function signature of the constructor that
we're actually taking ownership of this array. Let's fix that by using
UniquePtr<AudioDataValue[]> smart pointers to hold the data prior to
creating AudioData values, and for passing in to AudioData's
constructor. Using standard-er C++ things instead of our homegrown ones
is a good thing.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

Note AudioSinkWrapper can now report correct playback position when the media is video-only or audio-only.
We will handle the case where audio ends before video in next patch where it needs to switch to system clock when audio reaches the end.
The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.
