#5043: Audio skips when using timestretch

---------------------------+------------------------------------------------
 When I use multi-channel timestretch the audio will periodically skip back
 a few seconds.  The picture plays fine and the audio eventually skips
 forward to match.  I get a slew of "Audio buffer overflow, audio data
 lost", and "NVP: Video is xx frames ahead of audio..." messages when this
 happens.

 AFAICT the value of waud in audiooutputbase.cpp is not wrapping around to
 0 properly. This causes the above problem.  The attached patch fixes it.
