[PATCH] protos.h splitting, part 2 of 2

Hi all,
  the attached patch:
- finishes the job of splitting protos.h into individual components
- removes the inclusion of protos.h from most files
- cleans up leftover $Id$ and arch-tag comments
- cleans up some module initialization calls from #ifdef-d to NOP
style, as we have discussed on the -dev mailing-list a few days ago.

protos.h is still there, as it contains the prototypes for three
functions implemented in main.cc. Getting rid of that will require
some more effort.

It's been build-tested OK on all farm nodes where trunk builds; it may
mess some things up on windows port but it's currently impossible to
verify it.
Could you please review it?

Thanks.
