small adaptations to zipping integration
deactivate start script for copy way, zip trace file internally

This patch deactivates the start script for the Linux implementation
of the copy way, entailing some important changes to CpComm.
o the number of OS processes is determined from arguments in MP_start
o shared memory and semaphores are created and OS processes forked
  in MP_sync (after having parsed the RTS flags)
o after shutdown, the eventlog files are archived to a parevents
  file using integrated code.

Zlib support for archiving is currently disabled, as it will require
adding suitable linker flags, and might still have a subtle bugs
(I had added it initially, but had problems with the generated files).
