Update tests.

Fix test 5.3 which will fail if user does not have partition
in his SQUEUE_FORMAT.
Permit jobs to use specialized cores

The attached patch introduces a mechanism for sites to allow jobs
to use specialized resources.  Jobs take advantage of this
capability by designating --core-spec=0.

Correct job shared info

Correct Shared field in job state information seen by scontrol, sview, etc.
Merge branch 'slurm-14.03'
Add SchedulerParameters option build_queue_timeout

Add new SchedulerParameters option of build_queue_timeout to throttle how
much time can be consumed building the job queue for scheduling.
Print the array identification only if the job is an array.
Print Slurm error string in scontrol update job and reset the Slurm
errno before each call to the API.
in core_spec test, verify enabled

Don't test that core specialization works if it is disabled in
slurm.conf.
