9a84687a23 Bug 998179 - Refactor how MediaStreamGraph get and use their sample rate. r=roc
Use the sample rate passed to the OfflineAudioContext constructor in
MediaStreamGraph::CreateOfflineInstance, and pass the preferred mixer sample
rate to the (real time) MediaStreamGraph constructor.

Then, always use this sample rate for the lifetime of the graph.

This patch needed to pass the sample rate to the AudioMixer class to avoid
relying on globals like it was done before.

bb61e5a5d6 Bug 919215 - Start the AudioStream on creation when in low-latency mode, and let it underrun. r=roc
The BufferedAudioStream buffers the data it gets through the Write() calls and
what is consumed by the callback. This means that if the audio producer starts
Write()ing data right after Start()ing the stream, data will accumulate in this
buffer and won't be consumed. Eventually, the buffer will be of a certain size
before it begins to be consumed by the callback, and this means an
umcompressible latency (because the data will be written at more or less the
same rate as it is produced).

This patch start the BufferedAudioStream right away when it is created, dropping
the silent AudioSegment until it finds real data (and padding with silence is
then done at the beginning). The stream will underrun, but the callback will
synthetize silence, avoiding overbuffering in the BufferedAudioStream. This
ensures minimal latency cause by the buffering.

Note that the clock will still advance, so this will not change the behavior of
content that has leading silence.

8d0872c840 Bug 805254. Part 12: Simplify AudioSegment::WriteTo and related code now that the output format is known statically. r=kinetik
Also fixes what I think is a bug in InterleaveAndConvertBuffer converting S16 to S16.
Instead of clamping the volume, we should handle arbitrary volumes by falling back
to the float conversion path.

4dcad1fa98 Bug 805254. Part 8: Consolidate audio sample processing code using templates over the format types. r=kinetik
Replace nsAudioStream::Format with an AUDIO_OUTPUT_FORMAT enum value so we
can use it as a template parameter.

Introduce AudioSampleTraits<AudioSampleFormat> to give us access to the C++ type
corresponding to an enum value.

Move SampleToFloat/FloatToSample to AudioSampleFormat.h.

Introduce ConvertAudioSamples and ConvertAudioSamplesWithScale functions
and use them from various places.

Moves AudioDataValue to AudioSampleFormat.h. The name isn't great, but it'll do.
