Bug 747793 - Use a ring buffer for audio buffered by nsBufferedAudioStream.  Remove generic sample copy out with volume adjustment and replace with the lightly optimized version from nsNativeAudioStream.  Add a fast path for the unity volume case.  Bump cubeb's refill thread priority on Win32.  r=cpearce

This builds the opus reference library in media/libopus.
We support both fixed and floating point builds, switched
by MOZ_OPUS_FIXED. Currently this isn't defined by anything
but should probably offer a configure option, and default
to true on arm.

Thanks to Tim Terriberry for additional review.
