Previous logic could truncate CPU masks at 32-bits

(1 << x) where "x" is a uint64_t would treat "1" as an int and
roll over at 32-bits. Typecasting "1" to uint64_t eliminates
that and supports a full 64-bit value.

Update slurm.spec file to have seff depend on slurm-perlapi.

Make test more robust for compute nodes with large CPU counts.

This change fixes Slurm's ability to optimize selection of resources
for a job requesting feature counts where some of those node features
are currently inactive (require node reboot to claim).

when in use.

The problem here is the polling threads in the various acct_gather codes
were detached and could possibly still be polling after the plugin had
been unloaded making a seg fault with a backtrace like this...

The fix was to make the threads non-detached and join them before calling
a dlclose.

Whenever possible, avoid allocating nodes that require a reboot.
Previous logic failed to re-sort the job set table based upon
the need for rebooting to achieve the desired features (e.g. KNL
MCDRAM or CACHE mode).

Put header files in alphabetic order, No change in logic

trying to verify the cluster name (which may try to /create/ files or
directories) *before* dropping privs results in a fatal error as
slurmctld tries to create items which ultimately fail.  Moving
this process until after the privs and uid have changed allows
the process to succeed.

Bug 2728

Reject invalid step at submit time rather than leaving it queued.
Bug 2722 describes one of the use cases triggering the bug.

"Argument with 'nonnull' attribute passed null"

Minor update to commit 2fad3bcf
This leaves the files locked until file write completes.

Disable a job deadline test with no input time limit if the default
partition has a default time limit.
