906905aa43 Use a macro for aligning PCM chunks instead of explictly coding it each time.

a43df152c2 Collect the 16-bit signed range sample clipping routines scattered about, which can be optimized on armv6 and create firmware/export/dsp-util.h (for lack of better place right now).

22b6def065 Use playback channel directly for peakmeters and plugins using peak calculation. Also, for now, don't allow mixer playback to overlap recording, even if full duplex works.

5ff641fb81 Do some adjustments to alleviate IRAM congestion on some targets from r30097. Include removing pointless IRAM declarations in pcmbuf.c because that callback code runs at a fairly relaxed pace. M5 is still the biggest problem.

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.
