allocate calls.

Moved some "shared" node logic to avoid having it overwritten when
moving job config data from API structure.

   (macros.h)
 o Include macros.h in slurm_protocol_defs.h

 o moved DIST_* to SRUN_DIST_* to avoid conflicts with slurm API

* added commandline parseing to slurmctld
	( I haven't resolved all the problems between read_config )
* changed job_allocate_response_msg to resource_... to reflect the naming scheme better.
* added cpu info to resouce_allocate_response_msg
* fixed slurmctld to return resource allocate messages

Converted job unpack function to allocate memory (instead of setting
a pointer and freeing it - and aborting).

Fixed numerous minor bugs in job allocation RPCs.
Added numerous job allocation errors.
