Bug 4131

Simplify the step prefix process
and move it as early as possible in the step.

Since NO_VAL = SLURM_BATCH_SCRIPT, the else statement would only compare
the job_id and not the step_id, thus when a batch step was removed all
the steps from that job would be removed too. Then when attempting to
remove the extern step in the next iteration, it was already removed
and we were incorrectly erroring out.

Bug 4458.

Fix to purge old jobs using burst buffer if slurmctld daemon restarted
    after the job's burst buffer work was already completed.

Fix memory leak of MailDomain configuration string when slurmctld daemon
   is reconfigured.

Bug 4450

slurm_load_job() prior to 17.11 returns the error code in errno and not
in rc.  With the addition of 47175901 if a job is removed from memory
before sbatch checks for the job again, sbatch could get in an loop
checking for the job. This only happens if you have a very small
MinJobAge (<10) -- which is not recommended.

Bug 4431

If a pending federated job exists on clusters 2 and 3 and squeue is run
from cluster 1 then the active siblings can come and go depending on
which cluster returns the job info first and depending if that cluster
is the origin cluster or not. The origin cluster only knows where the
active siblings are.

from status commands.

Bug 4341

Add in strong_alias calls so these functions will appear in
libslurm and not just libslurmfull. Otherwise test7.3 can fail
due to a missing symbol if a gpu gres is allocated to the job.

Bug 4415.

This setting causes /unix to be omitted from the xauth string.
Simplify the regex to handle this by adding / to the earlier match and
dropping the /unix pattern.

Bug 4417.

bug 4400

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

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

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

Bug 4398.

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.

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).
