Cool!

I just committed a separation of audio and video EOF conditions to fix this.
AudioDecoderThread now sends an EOF when the audio stream ends.
IVideoDecoder::isEOF now takes a StreamSelect parameter, defaulted to
SS_ALL, so that individual stream EOFs or all stream EOFs may be checked. I
enabled the async tests, and they seem to work just fine now.
