Remove some SQUEUE output format environment variables set by
  default on Cray systems, which break some tests

AND should have been an OR.
Modify test to log more details on failure.

Group id was being overwritten by user id.

Writing and reading to a file on a slow shared filesytem could cause
this test to fail.

The filesystem may have problems removing and creating the same filename
quickly.

Correct description of the SLURMD_NODENAME environment variable
in the sbatch and srun man pages.

Also add some job time limits

Increase a sleep for slower step start times on a Cray
Make error message more detailed (add expected/actual count to message)

One memory leak fixed
Some other code moved around for better clarity

Run autogen.sh to pickup changes and resolve conflicts.

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.
