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.

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.

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.

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.

Some job fields can change in the course of scheduling. This patch
reinitializes previously adjusted job fields to their original value

bug 5185

Previously the function was only testing against the first partition in
the job_record. Now it detects if the job request is multi partition and
if so then loops through all of them until the job will run in any or
until the end of the list, returning the error code from the last one if
the job won't run in any partition.

Bug 5185

This can happen if burst buffer logic is broken

When requesting specific jobids with sacct, the starttime of the request
is 0, which will cause the time range to be outside of the
MaxQueryTimeRange range -- if specified. When requesting specific
jobids, sacct should be able to find the job whenever it started --
unless confined to a smaller range with -S and/or -E.
