sets new environment variable SLURM_CPUS_ON_NODE for use by LAM/MPI.
Also fixed bug in srun task distribution logic for block distribution
in heterogeneous cluster.

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

and/or job step(s) will have their resources de-allocated and be killed.
A resource allocation will not be release unless no job steps are active
for at least InactiveLimit seconds. DPCS jobs will be subject to this
forced de-allocation if they remain inactive for an extended period of
time, which can get SLURM and DPCS back in sync if DPCS does a cold-start.

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).

  - changed defs of HAVE_LIBELAN3 to HAVE_ELAN

Define new node configuration parameter for DOWN/DRAIN nodes: Reason=whatever.
Define node reason field for update and get info RPCs.

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).

configuration information downloaded.

in get config RPC.

   slurm_cred_t job credential.

   the old slurm_job_credential_t, which was one cred per job, to a
   one cred per *job step* scheme. Creds are now limited lifetime and
   cannot be replayed (cred is invalidated once used).

   removed old implementation signature/credential_utils.[ch] and
   replaced with slurm_cred.[ch].

Add MinNodes partition configuration option support.
Add min_nodes to partition data structures, save/restart, dump, print, etc.

Load and dump  AuthType and PluginDir config structure elements to get config RPC.

Initialize/free/set alloc_sid and alloc_node in API functions.
Pack/unpack/free new elements in job descriptor RPCs.

slurm_cancel_job RPC now takes signal argument.

   prolog is run as root and failure is reported as a non-zero return code
   from the launch tasks or launch batch job messages
   epilog is run as result of revoke credential message

New RPC added for slurmd to send batch_sid to slurmctld.

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

   response message

Also add exclude=node_list to allocate RPCs.

job time limit. Defined pack/unpack/free functions for RPC.

 o srun -d option updated to set slurmd-debuggging level
 o slurmd sends task launch resp message with list of pids
   (for totalview support)
 o Three Ctrl-C's in rapid succession to srun forcefully terminates the job.
 o Changed --kill-off to --no-kill

than single PID). Used for TotalView support.
