[PATCH 15/17] hurd: add proc_{get,set}_code

[Justus Winter]

Add routines to set and query the processes start_code and end_code
locations. Any executable segments loaded from the ELF binary are in
this range.

* hurd/process.defs: Add proc_{get,set}_code.
* hurd/process_reply.defs: Add proc_{get,set}_code.
* hurd/process_request.defs: Add proc_{get,set}_code_request.
