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.

6920a5be44 rockdoom: Mixing 512 samples in an interrupt handler is too much. Gigabeast FIFOs are very tight and it will channel swap and crackle. It's better to minimize time in the audio callback anyway so change it to 128. It should probably even be 64. Use faster saturation code too.

4597ebe24b Plugins that play sound must be sure to set inputs and outputs on audio muxed targets. Add strict adherence to the interface protocols. Make sure playback sets the playback output as well.

cc8f80ad9b Temporary fix for the high-pitched sounds on iPod: they should sound correct now, but the real problem (frequency adjustment) still needs fixing; this is merely a workaround.
