This should never happen, but is a nice safeguard.

Contiuation of 9a243a1a

Bug 6592

Test was relying on seeing future jobs which is no longer the way it
works.

What was happening in a maintenance reservation was every 5 seconds
the slurmctld was sending a message to the slurmdbd telling it the
node's down/drain state was in a maintenance state as well.  We really
only needed to know about this once.

to avoid having to send alias list for cloud nodes that exist in DNS.
This is especially important for large cloud environments (e.g.
thousands of nodes) as the alias list environment will be too large for
execve().

Bug 6589

Bug 6587

This is useful in a cloud environment where the nodes come and go out of
DNS.

Same as salloc/sbatch --gres option.

Bug 6582.

Bug 6387.

salloc --no-shell jobs aren't interactive, and won't respond to pings
from the slurmctld, so they were previously getting killed after
InactiveLimit seconds, even when they had a running step. InactiveLimit
no longer applies for salloc --no-shell jobs.

Bug 6560.

Fixes smail to handle change in slurmctld/agent.c#mail_job_info() output
introduced in commit 5f1cc8a8.
seff has incomplete job array support, but if one happens to come through
smail, at least let it print out what it can (i.e. the last array task in
the job array).

Bug 6536

Allow sites to use hostname as given by libc gethostname() instead of
the first domain used globally as hostname.

Bug 6532.

Fixed typo in sshare --help output and updated man page

Bug 6570

bug 6178

Causes x11_delete_xauth() to be called on a successfully unlink()'d
file if using local_xauthority causing an extra error message in the
logs.

Bug 3647.

Also set canonical links in the man pages while here.

Bug 6573.

X11 forwarding doesn't care about the screen number, so handle DISPLAY
environment variables without that present correctly.

E.g., both "localhost:10.0" and "localhost:10" are now handled, whereas
previously only the first form would have been accepted.

Bug 6372

Clear the JOB_STAGE_OUT flag once the stage out is complete.
