If a job is configured to be sent a signal when approaching its
timeout and the job is requeued after the signal is sent, then
resend the signal at the approriate time after requeue.
bug 1415

If the backfill scheduler can not start at the appointed time, say
because there are too many pending RPC, then only sleep 1 second
and try again rather than the full bf_interval (30 seconds by default).

Same logic was in both backfill plugin and slurmctld/job_scheduler.c
No change in logic

Bug 2130

Adopted processes didn't have access to the job's devices.

Bug 2130

When slurmctld processes a SIGHUP or "scontrol reconfig" it
makes sure that every pending batch job as a directory containing
script and environment files, cancelling any job that lacks the
files and purging any files without a job. When there are a large
number of jobs (in any state) and a large number of files, the
nested loops to do this can run for a very long time (minutes).
This change streamlines the processing for job arrays, which now
avoid creating their own script and environment files by using that
of their job array master record.

Full revert of c2fbf88f, 13b64c35 had caught part of this, but
this will revert it completely.  The code just wasn't needed in modern
Slurm.  It appears the patch came from an older version of Slurm that
didn't handle this correctly.

This reverts commit 29f25688.

Looks like this isn't needed, commit c2fbf88f doesn't appear to be needed
and is what is causing this issue.  c2fbf88f was added from an older
version of Slurm where this was already handled correctly in commit
815e5a44.
