It really works, but it's not future-proof as it relies on the global GL context that's going away soon. But it probably won't go away in Aurora 14, so this should at least allow us to ship Fennec 14.
Longer term, we need to do some message passing so we can get the LayerManager's OpenGL context's renderer id, from the OMTC thread.

For media resources whose streams are captured before the load has started, we shouldn't even start
an audio thread. This saves a lot of resources and ensures we don't see races between the audio thread
and the code that copies packets from the audio queue to the MediaStreams.
The first part just handles the case where nsAudioStream failed to allocate a stream. It won't be playing
anything, so instead of trying to get the audio position, just fall back to the media graph current time.
Otherwise GetPositionInFrames returns -1 and things go badly from there.
The second part simplifies the calculation of the next mCurrentTime to just make it based on real time.
We had some code to not let it advance past the end of a stream's buffer, but the next part will make that
unnecessary.
The third part is the real fix. When the new current time has advanced past mBlockingDecisionsMadeUntilTime,
that means the control loop didn't run in time to replenish the audio output buffers and keep up with its
other duties. Effectively all streams have been blocked between mBlockingDecisionsMadeUntilTime and
the new current time. Account for that by adding the difference as extra blocked time for every stream.
We only need to ensure that the stream is marked blocked from mBlockingDecisionsMadeUntilTime indefinitely
far into the future, and then update mBlockingDecisionsMadeUntilTime to the new current time, because the
code takes into account that only blocking decisions up to mBlockingDecisionsMadeUntilTime are valid.
This bug, introduced by the patch from bug 732233, caused us to wrongly reject
legitimate WebGL uniform setters, especially when doing a partial update of
a uniform array.
ErrorResult is in a separate header file so it can be included from all over the
place without having to pull in mozilla/dom/Utils.h and all the xpconnect gunk
that needs.
Fix a crash loading opus files when the media.opus.enabled pref is
false. The buffering code still tries to call our Time() method,
but without having read the headers we cannot perform the
conversion.
This commit adds a guard on mActive like the other ::Time
methods use.

This adds APIs suitable for calling from the new DOM bindings to WebGLContext and makes the XPCOM
versions of the WebGL context API call through to the new-binding versions.
