 -- Add new slurm.conf parameter ProctrackType (process tracking) and
    associated plugin in the slurmd module.

Change slurm_job_will_run() to not return a message, just an error code.

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

tests were change appropriately. This lets one fake a Linux cluster
without all of the BGL-specific logic.

Move pretty much all BGL-specific logic into that module and the
  associated plugin and make use of an opaque data object for
  maintaining the information.

Add new function to drain node (for use by select/bluegene node
  monitoring thread).

Map all nodes in cluster to a single front-end node.
Don't repeat ping/register/kill/etc. RPCs to all pseudo nodes, just the
  front-end.
Treat single message for some RPCs as representing all nodes in the
  cluster: register, ping responce, epilog complete, etc.

flag the required state saves. Perform the saves using synchronous I/O
from just one thread. Under heavy loads this results in much faster
responsiveness and lowers slurmctld's memory and CPU overhead considerably.

Create StateSaveLocation directory if changes via slurmctld reconfig

modifications were relatively minor - mostly changes in function
names or arguments.

"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.

Otherwise signal all steps associated with the job (unless individual job
steps are identified).

Allocate calls were using job table info in place after freeing mutex.
New logic copies data structures, frees mutex, sends message, and
then frees memory allocated for copy.

avoid highly fragmented resource allocations.
Add list of excluded nodes to job info dumpped and reported.
Fix how mis-matched RPC version number are handled. Let error code get
back to the API function.
Dump job state information upon each job's termination via plugin.
Re-issue incomplete write requests in job/partition state save.
Make slurmctld continue proper operation without any default partition
(gnats:317).
Add command/RPC to delete a partition.
Retry socket connection for slurmd/io.c as needed (gnats:253).

Fatal() no longer calls abort(), but terminates job using exit(1).

save on job_step completion. This should reduce the likelyhood of
information being lost on a slurmctld restart.
