Bug 6769

Consider jobs in COMPLETING state as being available immediatley for
a job will-run evaluation. This assumes the completion will happen
very soon after the test is run.

bug 6769

All of the select plugins were performing a duplicate resource free
for jobs in completing state when performing a will-run test for
new jobs. This would frequently result in underflow messages.

Bug 6769

Building off the prevoius commit, spank_option_getopt() is now valid in
more functions than before, so we document and enforce from where
spank_option_getopt() can safely be called and return ESPANK_NOT_AVAIL
if it is called from any invalid SPANK context.

Bug 7065.

When spank option callbacks are called, the options are added to a cache
in memory so that spank_option_getopt() can retrieve the options when
called. However, this was only happening when callbacks were called from
the local context, so we make sure that the options are added to the
cache when the callbacks are called from the remote context as well.

job_test_resv() - return ESLURM_RESERVATION_MAINT if all nodes
from the job partition are in a maintenance reservation.

Bug 7362.

If job requests feature(s) but the required nodes are in an advanced
reservation.

Bug 7362.

Previously the UnavailableNodes list could include nodes that don't
belong to the job partition.

Bug 7311

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

Revert 86b0bd39 which removed slurm.FAILURE from job_submit/lua.

In a76a9486 we replaced SLURM_ERROR by SLURM_FAILURE. This commit
restores slurm.FAILURE as an synonym of SLURM_ERROR for job_submit/lua
scripts, which is now considered depreciated in 19.05.
