Bug 4379

Can cause slurmstepd to crash, as rlimit_name was pointing to
part of the free'd env_name variable.

Bug 4409.

This patch has fixed the problem to me. We are going to do some more
verification later today and update.
But I would appreciate if somebody else can test it as well.

There was a list of pending pack job records under consideration
  for scheduling by the backfill plugin that was not being cleared
  between interations of the backfill scheduler resulting in various
  scheduling anomalies.
bug 4371, 4400

An abort was triggered here due to a pack job start failure.

This was causing a segfault of the slurmd on load since the while loop
could go into the

	if (f == 0) {

section and thus use the now freed array.

code dealing with how we need to keep track of it.

Bug 4405

For heterogeneous job steps, the srun --open-mode option default value will
    be set to "append".

Previous logic would fail if more than 2 pack groups implicitly
  specified in srun command.

Previous logic would delay the initiation of pack jobs until all
  components were submitted. The new logic will defer pack job
  scheduling based upon a new "pack_job_offset" field in the
  job submit request and NOT set a begin_time in the future.
  This will eliminate the pack job scheduling reason value
  of "BEGIN_TIME".

Fix for bug introduced in commit 9e0b976a
bug 4400

The regex in x11_set_xauth() did not match FQDNs because it was missing
a dot.

Bug 4398.

If a node's physical Boards, Sockets, Cores, Threads, etc.
  differ from configuration log using error() rather than info().
bug 4394

Add SchedulerParameters=whole_pack configuration parameter. If set, then
    hold, release and cancel operations on any component of a heterogeneous job
    will be applied to all components.
bug 4374

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.
bug 4379

Add SLURM_PACK_JOB_NODELIST to PrologSlurmctld and EpilogSlurmctld
    environment.
