of communication protocol over IBM Federation switch.
 -- Add new slurm.conf parameter ProctrackType (process tracking) and
    associated plugin in the slurmd module.

All work from <takao.hatazaki@hp.com>.

and slurmctld (specify different configuration file).

  to prevent things getting hosed if the table is re-read on SIGHUP.

"Scontrol abort" works. It was leaving a hung pthread due to a recent
   change.
Fix a couple of potential memory leaks
"switch_type" has been added to config data structure, un/pack, etc,
   but not yet reported to the user or documented yet.
The plugins now use function calls to get a their type and plugin directory
   from a common data structure rather than individually reading and
   parsing the configuration file.

These jobs are reported by slurmd on node registration. They are logged
but otherwise ignored by slurmctld. Several changes to slurmd logging
messaged to report job id and step id using %u format rather than %d
format (which shows no-allocate job id values as negative numbers).

WaitTime sets srun's default value for --wait. MaxJobCount sets
the maximum job count for slurmctld (replacing #define MAX_JOB_CNT).
MinJobAge sets the minimum job purrge age for slurmctld (replacing
#define MIN_JOB_AGE).

job, step, node, and partition info.
Add new function to free slurm_credential from RPC response.

   slurm_send_recv_node_msg(), slurm_send_recv_rc_msg(), etc.
 o Fixed fd leak in agent.c using slurm_send_recv_rc_msg() w/ timeout.

   slurm_protocol_socket_implementation.c
 o Added new functions slurm_send_recv*rc_msg() for handing common
   mode of sending a message and receiving only a "return code" message.
 o Overhauled existing code and performed general cleanup.

All references to header files changed to new pathname.

New RPC added for slurmd to send batch_sid to slurmctld.

New RPC defined to map local pid into slurm job id.

common needs to read anyway to route communications (avoid second read
by other tools).

read_config functions.

bad message. Functions now return SLURM_ERROR on bad unpack instead
of assert failure.

(so shutdown command can shutdown both servers).

a slurm_addr.

that includes a buffer pointer, size, and offset. The buffer is automatically
expanded as space is needed.

removed old send/recv buffer calls, they weren't being used and aren't compatible with the new auth credential transport changes

adde fcntl to slurm_protocol for non-blocking io

Merge all error functions into slurm_errno.[ch].
Convert error codes from #define to enum.

   of directly to a stream.

fixed launch_task_response msg
added slurm_protocol and slurmd errnos to slurm_errno.h
added print_slurm_addr to src/common/slurm_protocol_api.c
added print_slurm_credential to src/common/slurm_protocol_util.c
cleaned up debug printing and error reporting for src/slurmd/shmem_struct.c
more cleanup
etc

added a few comments and slurm_protocol_errno entries.
More little code cleanup

moved a few more signal calls to posix standard sigaction
