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.

9542499e15 Bug 805254. Part 4: Remove FORMAT_U8 from nsAudioStream::SampleFormat. r=kinetik 
We also give nsWaveReader its own separate format enum.

2cbb708232 Bug 805254. Part 2: Rename nsAudioStream::GetFormat() to Format(), make it static, and use it instead of the MOZ_AUDIO_DATA_FORMAT macro. r=kinetik 
Part 8 mostly replaces this patch, but it's quite difficult to reorder the patches to avoid this one.
