LibDSP+Piano: Convert DSP APIs to accept entire sample ranges

Browse source 
This has mainly performance benefits, so that we only need to call into
all processors once for every audio buffer segment. It requires
adjusting quite some logic in most processors and in Track, as we have
to consider a larger collection of notes and samples at each step.

There's some cautionary TODOs in the currently unused LibDSP tracks
because they don't do things properly yet.
