bug 1207

Add new slurm_load_node flag of SHOW_MIXED, which will change a node's
state from ALLOCATED to MIXED by comparing the number of CPUs allocated
against the total CPU count on each node
bug 1209

The perl API sbcast function included a step ID, which is NOT in v14.11, on v15.08

Previous logic would fail an assert

If the slurm.conf file includes other files and those files do
not include an absolute path name, they will be taken from the
same directory as slurm.conf. Previously it used the search path.

Use default_partition by default for the test

Returned test passed, when it should have failed because of bad
variable name.

This matches the value in version 14.03

We've seen slurmctld crashes due to negative job array indices.

add field to slurmctld job structure, save/restore field,
Add support to view/set in scontrol and sview
Add support to view in squeue
Validate job update string lengths

Add "--bb" (burst buffer specification) option to salloc, sbatch, and srun.
Information reaches slurmctld, but is not processed more (yet).

The previous patch should work in most cases, but this should
work more reliably and the comment is more clear
bug 1196

it was looking at 08 as an octal number and not printing it correctly.

This patch forces it to be looked at as a base 10 int.

I did the same thing for the SLURM_API_VERSION just to be safe since it
used the same kind of logic.

This reverts commit 7e65f924.

Also don't fail a job that could not be requeued because it was
already pending. This was not actually observed, but appeared
to be a possible race condition discovered in working on bug 1196

BGQ: Fix race condition when job fails due to hardware failure and is
requeued. Previous code could result in slurmctld abort with NULL pointer.

The slurm_sbcast_lookup() API was recently changed to take a step ID.
This changes the Perl API to match that.
