netz: switch printf's to TRACEs.

oops, should have done this a long time ago.
move freeproc loading stuff into a separate file

situ config is getting unwieldy...
move all transferlib code into fproc.

the only thing in the main file now is the actual array... maybe
we should move that out as well.
move posix instrumentation to its own file.

hopefully we can abstract out every target soon enough.
