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).

   - fixes to help ensure slurmd uses the same key for shared memory
     on a restart (to avoid losing track of jobs)
   - slurmd only runs one launch thread at a time
   - fix bug in slurmd where multiple threads used same address space
     for connecting client address.
   - srun always sends SIGKILL to job step before issuing complete request
   - Changed short string for draining nodes to drng from drain.
   - srun default launch message timeout increased to 5s.

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

Add command/RPC to delete a partition.
Retry socket connection for slurmd/io.c as needed (gnats:253).
