This gets the alsa target working nicely for mmapped outout. I'm not certain, but I think it will even deal with NPOT buffer sizes (I copied the code from libasound's sample pcm.c, thus the uncertainty). Non-mmapped output isn't supported yet, but the alsa target now works nicely for pull rendering. However, some work still needs to be done for recovery failure: either disable the sound system, or restart the driver entirely (preferable).
