There were several local strcmp functions that handled NULL input.
I removed the local functions and changed the code to use xstrcmp
from src/common/xstring.c instead. No changed in functionality.

Add support for job dependencies jointed with OR operator (e.g.
"--depend=afterok:123?afternotok:124").

Correct tracking of licenses for suspended jobs on slurmctld reconfigure or
restart. Previously licenses for suspended jobs were not counted, so
the license count could be exceeded with those jobs get resumed.

commit a9dc50d4.

Add sbcast support for file transfer to resources allocated to a job step
rather than a job allocation.

be the SLURM_*_PROTOCOL_VERSION.

bug 1178

No change in functionality, just eliminated a call to time().

Insure that a file needed for the test exists. This problem happens
on emulated cray systems.

Refine commit 5f89223f based upon
feedback from David Gloe:
* It's not only MPI jobs, but anything that uses PMI. That includes MPI,
shmem, etc, so you may want to reword the error message.
* I added the terminated flag because if multiple tasks on a node exit,
you would get an error message from each of them. That reduces it to one
error message per node. Cray bug 810310 prompted that change.
* Since we're now relying on --kill-on-bad-exit, I think we should update
the Cray slurm.conf template to default to 1 (set KillOnBadExit=1 in
contribs/cray/slurm.conf.template).

Treat Cray MPI job calling exit() without mpi_fini() as fatal error for
that specific task and let srun handle all timeout logic.
Previous logic would cancel the entire job step and srun options
for wait time and kill on exit were ignored. The new logic provides
users with the following type of response:

$ srun -n3 -K0 -N3 --wait=60 ./tmp
Task:0 Cycle:1
Task:2 Cycle:1
Task:1 Cycle:1
Task:0 Cycle:2
Task:2 Cycle:2
slurmstepd: step 14927.0 task 1 exited without calling mpi_fini()
srun: error: tux2: task 1: Killed
Task:0 Cycle:3
Task:2 Cycle:3
Task:0 Cycle:4
...
