0661e8b253 Bug 1062293 - Add specialized logging to track the lifetime state change of MediaStreamGraphs r=jesup 
As noted in the comment, it is very useful to have this interleaved with the ADB
logcat on Android/b2g, because this way we can correlate gecko state with the
state of the Android HAL.

b76a30bb3f Bug 848954 - Part 9 - Allow to pass in hints when getting a reference to a MediaStreamGraph to get the right driver started as soon as possible. r=roc 
This is useful because some platform have rather slow audio stream
initialization time, especially the first time an audio stream is created for
the process.

We put in telemetry probes to measure that:
First stream opened for the process:
http://telemetry.mozilla.org/#filter=nightly%2F33%2FAUDIOSTREAM_FIRST_OPEN_MS&aggregates=multiselect-all!Submissions!Mean!5th%20percentile!25th%20percentile!median!75th%20percentile!95th%20percentile&evoOver=Builds&locked=true&sanitize=true&renderhistogram=Graph

Subsequent streams:
http://telemetry.mozilla.org/#filter=nightly%2F33%2FAUDIOSTREAM_LATER_OPEN_MS&aggregates=multiselect-all!Submissions!Mean!5th%20percentile!25th%20percentile!median!75th%20percentile!95th%20percentile&evoOver=Builds&locked=true&sanitize=true&renderhistogram=Graph

679fac5442 Bug 848954 - Part 7 - Get rid of the stack allocated message queue. r=roc 
In the next patches, when the AudioDriver will be implemented, the audio backend
thread (that we don't control), will return from the stack frame where the
nsTArray that allows the MSG thread to exchange message queues in a efficient
manner with the main thread. We put it in the MediaStreamGraph to avoid adding
an allocation/deallocation per iteration on the MSG thread.

In addition, the graph will be able to run on different threads during its
lifetime, so we can't guarantee a stable stack frame to allocate things on
anymore.

The array are renamed with meaningful names, explaining the double-buffering
pattern: the back queue is filled by the main thread, and is swapped with the
front queue that is processed by the MSG thread.

Arrays accesses are synchronized using the driver's monitor.

c408e4099c b=932400 change stream ordering to get feedback DelayNode output before supplying input r=roc 
Previously downstream nodes from DelayNodes in cycles sometimes received stale
output from the previous MSG iteration.

Also, if two cycles share a common path, they will now *both* be treated as
cycles, either by muting or by enforcing minimum delay.  Previously, marking
one cycle first could prevent detection of other cycles in the same SCC.

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.
