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

The lower limit of 1024 may be too short for srun with large-scale
jobs, and lead to problems processing task completion messages in a
timely fashion.

Rather than adjust that, unify the two separate macros into
SLURM_DEFAULT_LISTEN_BACKLOG with the higer 4096 value.

Bug 5164.

Without Delegate=yes, systemd will "fix" the cgroup hierarchies whenever
'systemctl daemon-reload' is called, which will then remove any
restrictions placed on memory or device access for a given job.

This is a problem especially since 'systemctl daemon-reload' may be called
automatically by rpm/yum or a variety of config file mangers, leading to
jobs escaping from slurmd/slurmstepd's control.

This setting should work for systemd versions >= 205.

Bug 5292.

When a job with time_end=0 and TRES null exists from an association that is
currently inside a reservation, the hourly rollup segfaults.

srun was already fixed in b7053bda (Bug 3294).

Bug 5126

'have_innodb' is deprecated.

Bug 5317.

When printing arrays in squeue and setting the SLURM_BITSTR_LEN variable to 0
or to NULL, the length of the output defaulted to 64, when the documentation
says it will default to "unlimited". This patch fixes this situation.

Bug 5440

Logic was switched around in 17.11, enable_user_top is now the
correct option.

Bug 5165.

This is not working reliably even when setting
SchedulerParameters=enable_hetero_steps and/or using OpenMPI with Slurm's
mpi/pmi2, as it was previously documented.

Bug 5309.

Documented, and code reads as needing, the node lock. But these
were incorrectly set as the job locks.

Bug 5394.

Needs the job write lock, as it may change job status not just node
status. Especially after commit 33e352a6.

Bug 5406.

Previously, usage was just CPU-seconds. However, since
TresBillingWeights has been added, usage gets calculated from that, or
it's just CPU-seconds if TresBillingWeights isn't defined.

Bug 5434.

Add errno to info message in the SlurmDBD log, and pass the actual
errno back to the sacctmgr process so the user can see it.

Bug 5152.

- avoid `abort()` when collective is failed
- added logging of coll details for fail cases

Bug 5067

Note, this is setting it up so we can use defunct functions.  It will
probably need to be properly fixed in a future version so we don't
do this.

Bug 5390

Continuation of 923c9b37.

There is a delay in the cgroup system when moving a PID from one cgroup
to another. It is usually short, but if we don't wait for the PID to
move before removing cgroup directories the PID previously belonged to,
we could leak cgroups. This was previously fixed in the cpuset and
devices subsystems. This uses the same logic to fix the freezer
subsystem.

Bug 5082.

cpuset and devices subsystems have duplicate code to cleanup the cgroup
and prevent leaking cgroups by moving the process to the root cgroup and
waiting for it to be moved.

Move this duplicate code to a common function so it can be used later by
the freezer subsystem.

So that multiple nodes changes will be reported on one line rather than one
line per node. Otherwise this could lead to performance issues when reloading
slurmctld in big systems.

Bug4980

Slurm numbers the cores using an abstract index, starting from CPU 0
on the first socket, core, thread, and continuing until N on the last socket,
last core, last thread. Explain that in the documentation.

Currently, no caller checks the return code.

Bug 5164

Can't have # character in the password since it is treated as a comment.

Bug 5294

Only produces a whitespace difference in configure. Inadvertently
introduced by commit 103ebaac.

Bug 5335.

Firefox handles flex differently than Chrome. When flex is set to 1,
the flex item does not respect the flex container's bounds, causing
text to be cutoff.

Bug 5339.

Some job fields can change in the course of scheduling. This patch
reinitializes previously adjusted job fields to their original value
when validating the job memory in multi-partition requests.
