cd8e11b463 Tweak some PCM drivers for less typecasting with the data pointer.
Yeah, sizeof (void) here with GCC is 1. If something has a problem
with that, we'll set it straight.

286a4c5caa Revise the PCM callback system after adding multichannel audio.
Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

9d9d867bce Nokia N900: Implement pcm_play_lock() / pcm_play_unlock()
Shamelessly stolen from pcm-android.c

Thanks to Michael Sevakis for pointing out
that pcm_play_lock() is actually needed.

4db3e89652 Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it.

a2b6703a36 Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well.
