6a633ae6b2 Bug 1062293 - Ensure the graph stays alive when doing driver switches and audio stream shutdown operations. r=jesup 
This basically gets a grip on the graph while doing driver switches operations
on another thread (system thread or audio thread), because those can take time.
Because the graph is refcounted, it'll be freed when the last operation
finishes, which is what we want.

This patch also only allows driver switching when the graph is in state
LIFECYCLE_RUNNING, which is what we want anyway.

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.

5d75646bd9 Bug 848954 - Part 32 - Disable MSG sleep. r=padenot 
This has a race somewhere, so we disable it for now.

The real fix will come from the Web Audio API Suspend API [0]

4d9c2e35fb Bug 848954 - Part 28 - Properly stop the driver when shutting down the graph. r=jesup

1e9aca6c1d Bug 848954 - Part 28 - Allow to set a driver twice per iteration iff the second driver is an audio driver. r=jesup 
This should not happen, but does. Somehow, we detect that there is no track with
audio in the graph, during the graph updates (after having ran the messages),
and then, during CreateOrDestroyAudioStream, there is a track with audio.

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.
