e5e74aa411 Bug 836599 - Part 12: Fix the lifetime management of the Web Audio graph in presence of OfflineAudioContexts; r=roc 
Here we make the non-realtime graphs to go to sleep until they're shut down
from the main thread.  This allows us to use the common forced shutdown code
path in MediaStreamGraphImpl::RunThread.  We also need to delete the graph
object when the last message is dispatched to it.

In addition, we need to make sure that the AudioNodes also get released when
they're no longer needed.  To do this, we need for force the SelfReference of
AudioBufferSourceNodes to be released when the context is shut down, and also
trigger the destruction of the graph there.

e27939f54d Bug 836599 - Part 10: Use the non-realtime MediaStreamGraph API and a custom destination node engine for OfflineAudioContext; r=roc 
We offload most of the logic for OfflineAudioContext to the destination node,
since that's where the sample recording needs to happen, so doing this will
make the code simpler.

2d790c190b Bug 853298 - Part 1: Switch the ownership model of audio nodes to be based the cycle collector with wrapper caches; r=roc 
Here is what this patch does:
 * Got rid of the JSBindingFinalized stuff
 * Made all nodes wrappercached
 * Started to hold a self reference while the AudioBufferSourceNode is playing back
 * Converted the input references to weak references
 * Got rid of all of the SetProduceOwnOutput and UpdateOutputEnded logic

The nodes are now collected by the cycle collector which calls into
DisconnectFromGraph which drops the references to other nodes and destroys the
media stream.  Note that most of the cycles that are now inherent in the
ownership model are between nodes and their AudioParams (that is, the cycles
not created by content.)

6d8b72a707 Bug 804387. Part 9: Update WebAudio implementation to integrate with AudioNodeStream. r=ehsan 
This is a mega-patch that was too hard to disentangle. Here's what it does:
-- Create infrastructure around AudioNode::UpdateOutputEnded to detect
when a node can no longer produce any output. When that becomes true,
disconnect it from the AudioNode graph.
-- Have AudioNode implement JSBindingFinalized to use as input in
UpdateOutputEnded.
-- Give every AudioNode a MediaStream, and give every connection
a MediaInputPort.
-- Actually play the audio that reaches the AudioContext's destination node.
-- Force AudioContext to use the audio sample rate defined by MediaStreamGraph.
-- Fix AudioBufferSourceNode's start and stop methods to possibly throw and
take default 'when' parameters.
-- Create an AudioNodeStream for AudioBufferSourceNode and give it a
AudioBufferSourceNodeEngine that does what's needed. Set parameters for
this engine in the start() and stop() methods.
-- Create AudioBuffer::GetThreadSharedChannelsForRate, which is responsible
for stealing the contents of any JS array buffers, and bundling them up
into a thread-shared read-only buffer object which can be used as
part of an AudioChunk. This method will also be responsible for
resampling and caching as necessary.

5366306b68 Bug 793294 - Implement AudioBuffer; r=bzbarsky,smaug 
This is the full implementation of the AudioBuffer object.  There are
two ways to create these objects from an audio context and this patch
implements only one of them.

The construction of the AudioBuffer object is a two step process: the
object should be created with operator new first, and then
InitializeBuffers should be called on it.  InitializeBuffers is
fallible, because it uses the JS API to create the underlying typed
arrays, but that's fine, since the length of the buffers comes from web
content, and we don't want to use infallible allocations for those
anyways.

We hold on to the JS objects from the C++ implementation, and trace
through all of those objects, so that a GC does not kill those object
without us knowing.

The buffer should be possible to manipulate from both C++ and JS, and
the C++ object probably needs to support a set of methods for the C++
callers at some point.
