Cleanup and simplify latest DSP code incarnation.

Browse source 
Some things can just be a bit simpler in handling the list of stages
and some things, especially format change handling, can be simplified
for each stage implementation. Format changes are sent through the
configure() callback.

Hide some internal details and variables from processing stages and
let the core deal with it.

Do some miscellaneous cleanup and keep things a bit better factored.
