WaitForAudioToPlay() and IsPlaybackContinuing() should run in the same monitor to avoid |mPlaying| changes in-between.

It is possible for |mPlaying| to become false before IsPlaybackContinuing() acquiring the monitor. Then AudioStream::Resume() won't be called in IsPlaybackContinuing(). The rest of the code will run with the paused audio stream and assertion will fail.

This condition should hold for it is the same one to exit the while loop.

When |mStopAudioThread| is false, AudioQueue().AtEndOfStream() must be true for the reason above. Also we have to check |mPlaying| again here for it can change again while we are outside of monitor.

Thanks.

Strangely, I fixed this exact bug the same way... but I have no idea where my fix went, obviously never made it to Bugzilla. :-/
