Michael Sevakis 5857c44017 Refactor audio thread to run both recording and playback. 
Eliminates the pcmrec thread and keeps playback and recording engine
operation mutually-exclusive.

audio_thread.c contains the audio thread which branches to the
correct engine depending upon the request. It also handles the main
audio initialization.

Moves pcm_init into main.c just before dsp_init because I don't want
that one in audio_init in the new file.

(Also makes revision df6e1bc pointless ;)
