Comment:

 (In [26653]) Remove VideoBuffers::WaitForAvailable

 I've confirmed this is causing deadlocks in DVD playback. Given that it
 is only used in one place (MythPlayer::DecoderGetFrame), I've replaced
 that usage with a simple loop. VideoBuffers no doubt could use some
 additional internal locking but EnoughFreeFrames has been in use
 unprotected for years, so there is probably no real risk.

 Closes #8854
