Further unified HAL and HEL mixing, and added some more intelligence to
prebuffering, with some basic prebuffer canceling support, to get rid of
mixing delays in Half-Life. Used a very small waveout buffer queue in HEL
mode, using a callback to queue additional buffers, to get rid of
playback delays in Half-Life. Fixed a couple of bugs.
