Bug 1533

Fix bug that can permit someone to kill job array belonging to another user.

Fix support for --mem=0 (all memory of a node) with select/cons_res plugin.
Previously the job would not have it's memory constrained, but it would not
make that memory unavailable to other jobs either.
bug 1526

This was previously added to v14.11

Added new SchedulerParameters value of bf_min_age_reserve. The backfill
scheduler will not reserve resources for pending jobs until they have
been pending for at least the specified number of seconds. This can be
valuable if jobs lack time limits or all time limits have the same value.

Increase maximum MaxArraySize configuration parameter value from 1,000,001
to 4,000,001.

For job running under a debugger, if the exec of the task fails, then
cancel its I/O and abort immediately rather than waiting 60 seconds for
I/O timeout.

Bug 1469

The /root/.my.cnf would typically contain the login credentials for
root.  If those are needed for Slurm, then it should be checking
that directory.

I'll also note that typically the $HOME/.my.cnf file would be
checked last rather than first.

we came across the following error message in the slurmctld logs when
using non-consumable resources:

error: gres/potion: job 39 dealloc of node node1 bad node_offset 0 count
is 0

The error comes from _job_dealloc():

node_gres_data=0x7f8a18000b70, node_offset=0, gres_name=0x1999e00

The cause of this problem is that _node_state_dup() in gres.c does not
duplicate the no_consume flag.
The cr_ptr passed to _rm_job_from_nodes() is created with _dup_cr()
which calls _node_state_dup().

Below is a simple patch to fix the problem. A "future-proof" alternative
might be to memcpy() from gres_ptr to new_gres and
only handle pointers separately.

Add SLURM_JOB_GPUS environment variable to those available in Prolog.
Also add list of environment variables available in the various
prologs and epilogs on the web page.
