Many cosmetic modifications to eliminate warning message from GCC version
4.6 compiler, mostly due to unused variables.

Permit administrator to change a job's QOS to any value without validating
the job's owner has permission to use that QOS. Based upon patch by Phil
Eckert (LLNL).

Modify advance reservation to accept multiple specific block sizes rather
than a single node count. This is very important for BlueGene systems.

Modify srun's SIGINT handling logic timer (two SIGINTs within one second) to
be based microsecond rather than second timer.

Avoid clearing a job's reason from JobHeldAdmin or JobHeldUser when it is
otherwise updated using scontrol or sview commands. Patch based upon work
by Phil Eckert (LLNL).

Do not remove the backup slurmctld's pid file when it assumes control, only
when it actually shuts down. Patch from Andriy Grytsenko (Massive Solutions
Limited).

variable wasn't initialized in the job structure making it so that job
wouldn't run.

greatly.

conn_types in a block definition.

allow them on Q systems.

allocation with jobs running on blocks that don't exist in the static
setup.

and vice versa the node->base partition lists will be displayed if setup
in your .slurm/sviewrc file.

Fix bug which would crash slurmcld if job's owner (not root) tries to clear
a job's licenses by setting value to "".

If a job is deferred due to partition limits, then re-test those limits
after a partition is modified. Patch from Don Lipari.

if you were emulating a system.

when we are on a small block, not a regular one.

incorrectly.

position in the block instead of absolute.

If salloc was run as interactive, with job control, reset the foreground
process group of the terminal to the process group of the parent pid before
exiting. Patch from Don Albert, Bull.

Add cray.conf parameter of SyncTimeout, maximum time to defer job
scheduling if SLURM node or job state are out of synchronization with ALPS.

_job_create() consistent with similar logic in select_nodes().
