Bug 4393.

Running "scontrol reconfig" re-initialized some arrays/lists without
  clearing the previous values, resulting in a memory leak.

As reported by Valgrind

Previous logic would continuously report command not responding,
  but not exit the wait loop. Only test15.# checked so far

Fix logic so that we can find all components of a pack job if the
  submit fails. Populate the "pack_job_list" field on a pack job
  leader if some later component can't be submitted.

Correct printing error type based upon errno rather than returned rc.

If PrologSlurmctld fails for pack job leader then kill all
    components of the job.

Add SLURM_PACK_JOB_NODELIST to PrologSlurmctld and EpilogSlurmctld
    environment.

bug 4370

Prevent scheduling deadlock with multiple components of heterogeneous job
    in different partitions (i.e. one heterogeneous job component is higher
    priority in one partition and another component is lower priority in a
    different partition).
bug 4370

Issue could be reproduced by restarting slurmctld after a heterogeneous job
finished, but before MinJobAge time passed. Since the pack_job_list
job_record memeber wasn't saved/loaded to/from the job_state, the function
_validate_pack_jobs() is responsible for rebuilding the pack_job_list. Issue
was that the function was skiping the rebuild work for finished jobs, thus
other functions like the thread responsible for purging old jobs was failing
to iterate over a NULL pack_job_list which was never rebuilt.

Bug 4383.

If run from srun and lua job submit plugin sets environment, slurmctld
crashes.

Bug#4247

From within slurm_job_submit():
	job_desc.pack_job_offset

From within slurm_job_modify():
	job_rec.pack_job_id
	job_rec.pack_job_id_set
	job_rec.pack_job_offset

Bug 4372.

bug 4339

added some additional checks to prevent segfaults in some basic situations.
Bug 4247

bug 4368

Add SLURM_PACK_JOB_ID and SLURM_PACK_JOB_OFFSET to PrologSlurmctld and
  EpilogSlurmctld environment
bug 4379

Avoid srun abort trying to run on heterogeneous job component that has
    ended.
bug 4366

bug 4374

Do so even if pack-group 0 is completed, so long as not all components are completed
bug 4374

In a prior incarnation of the patch that introduced it,
it was MaxQueryTimeLimit, and that was not updated with
the code base when changed.

Bug 4365.

Update slurm.spec and slurm.spec-legacy as well

Bug 4323.

This now matches the sinfo documentation.

Bug 4306.

The race condition this is avoiding has been fixed elsewhere.
