da3263b6c1 b=857610 handle DelayNode channel count changes and separate buffer read and write r=padenot 
The basic idea is to write out the signal that came in with the same number of
channels as it had when it came in.  Things get a bit more complicated when
one output block may be derived from more than one input block, each having
different numbers of channels.  When this happens, the input blocks with fewer
channels are upmixed, so as not to lose (or distort) any signal in the block
with more channels.

HRTFPanner no longer uses exponential decay (with time constant 20ms) for
delay changes, but a smoother linear transition during cross-fade time (~45ms).

7d56e6d0f7 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.

4bdf74085e Bug 779715. Part 1: Add basic support for ProcessedMediaStreams. r=jesup 
The main thing this patch does is to add ProcessedMediaStream objects and
MediaInputPorts connecting streams. ProcessedMediaStreams are an abstract
class that doesn't constrain what processing is actually performed, except
that for now we assume a stream's processing depends only on its inputs
window of data between mCurrentTime and mStateComputedTime.
This patch reorganizes the way the blocking status of each stream is computed.
The streams are partitioned into groups so that every stream which can affect
the blocking status of another stream is in the same group as that other stream.
We also add a pass to order the streams by dependency so we can process the streams
in order of dependency; this pass also identifies the streams that form part of a
cycle.
