Cray - Fix for launching batch step within an existing job allocation.
bug 1509

Change check of batch step ID from NO_VAL to SLURM_BATCH_SCRIPT
  for better consistency.

Conflicts:
	src/slurmd/slurmstepd/task.c
	src/squeue/print.c

This should not be a problem in v14.03, but the logic will be
  important in v14.11 due to larger job arrays being supported.

Make sure variables are initialized before passing a pointer to
  them as a function argument. The variable is set in the underlying
  function, so this is mostly cosmetic.

Bug 1492

For job running under a debugger, if the exec of the task fails, then
cancel its I/O and abort immediately rather than waiting 60 seconds for
I/O timeout.

Add missing arguments to slurm_sched_p_newalloc/slurm_sched_p_freealloc
documentation.

Improved logging and some code restructuring. No change in logic.
