Add function to find job array element record
Add job array depenency support

Add support for dependencies of job array elements (e.g.
"sbatch --depend=afterok:123_4 ..."). This does not support
depenendencies of ALL job array elements, only individual job
array elements.
Rewrote most of 21.30 to work directly off limits instead of around the
limits
Handle situation to avoid shared nodes
return error if any of the inc tests fail
Add support for dependency on full job array
qsub wrapper, add warning for -S option
qsub command enhancements

Add support for -W block=true	(wait for job completion)
Clear PBS_NODEFILE environment variable

sched/wiki, sched/wiki2 - Fix to allow job start

Fix to work with change logic introduced in Slurm version 2.6.3
scheduling logic which prevented Maui/Moab from starting jobs.
Add more documentation about node reboot state
Priority/multifactor - minor logging improvements
Fix for used_cpu_run_secs bad calcuation

Add argument to priority plugin's priority_p_reconfig function to note
when the association and QOS used_cpu_run_secs field has been reset.
Without this flag, we remove time on "scontrol setdebug" or
"scontrol setdebugflag" that can result in used_cpu_run_secs
going negative or otherwise get bad values.
Correction to logic added in commit 6d7931896a9bc2bc2f4eac31b15b284e939233e9
bug 423
Updated the QOS limits documentation and man page.
Priority/multifactor - check for storage enforce

Avoid decrementing grp_used_cpu_run_secs if we are not enforcing
accounting limits. Without this change, the plugin will decrement
times from zero cpu used times (i.e decrement an uninitialized
variable).
