Modify scontrol requeue and requeue_hold commands to accept comma
  delimited list of job IDs.
bug 1929

Previously, scontrol would generate an error if passed a comma
  delimited list of job IDs. A space delimited list would be
  accepted. This increases compatability with some other Slurm
  commands.

If GRES are associated with specific CPUs and a job allocation includes
GRES, which are not associated with the specific CPUs allocated to the
job, then when the job is deallocated, an underflow error results. To
reproduce:

gres.conf:
Name=gpu File=/dev/tty0 CPUs=0-5
Name=gpu File=/dev/tty1 CPUs=6-11
Name=gpu File=/dev/tty2 CPUs=12-17
Name=gpu File=/dev/tty3 CPUs=18-23

Then
$ srun --gres=gpu:2 -N1 --ntasks-per-node=2 hostname

In slurmctld log file:
error: gres/gpu: job 695 dealloc node smd1 topo gres count underflow

Logic modified to increment the count based upon the specific GRES
actually allocated, ignoring the associated CPUs (too late to consider
that after the GRES as picked).

Also a very minor sanity check in job_mgr.c to make sure we at least have
a task count.  This shouldn't matter, but just to be as robust as possible.

only 1 job was accounted (against MaxSubmitJob) for when an array was
submitted.

Correct counting for job array limits, job count limit underflow possible
    when master cancellation of master job record.

I've noticed that parameter JobCheckpointDir has a (from my point of view) inconsistent behavior.

* in sbatch executions, it is exported as CWD
* in srun it is also exported as CWD,
* except when it is manually set with "--checkpoint-dir=dir". If so, that value is exported.
* value defined in slurm.conf is, as far as I know, never read.

I have created this small patch to correct that behaviour. Now it is exported with the value configured on slurm.conf. If nothing is set, returned value is the defined on common/read_config.h,
