Bug 6878

Brought the option in line with the "numtasks" option you use when
not specifying --step. Preserved backwards compatbility for "numtask"
for steps. Also upated docs and expect test.

Wrong variable was used.  This works fine for 18.08, but in 19.05 this
code doesn't work correctly.

Bug 6625.

These are conditions that need to remain constant until something
changes on the job to reevaluate.

What was happening here is you had to not be >= operator to have the old
limits removed.  This makes it so it always happens.

Before we went up the tree to the next assoc_ptr.  As we validate an
association on the id as well as the uid the assoc_ptr was eventually
going to become invalid.  Setting it to NULL here solves a bunch of
issues with things later on.

Don't abort when the job doesn't have an association that was removed before the job was able to make it to the database.

Bug 6625

The backfill scheduler keeps a local list of job pointers. Since the
backfill scheduler yields locks, it's possible for pending jobs to be
canceled and purged in these yield periods. The backfill scheduler then
has pointers to now invalid memory, and dereferencing those pointers is
undefined behavior and may result in a segfault.

This commit prevents purging jobs while the backfill scheduler is
running.

Bug 6621

The next patch will use slurmctld_diag_stats.bf_active to determine
if we can purge jobs or not.
