Clean up peak calculating code.
Mixer needn't keep peak data around that will never be used. Just
pass pcm_peaks structure to it instead of allocating for every
channel. Plugin API becomes incompatible.
vu_meter digital mode was still using global peak calculation;
switch it to playback channel like the rest.
Remove some accumulated soil peaks inside pcm.c and make it more
generic.
