Stop searching sbatch scripts for #PBS directives after 100 lines of
    non-comments. Stop parsing #PBS or #SLURM directives after 1024 characters
    into a line. Required for decent perforamnce with huge scripts.

Previously only supported by SlurmUser and root.

Previously only reserved space for one task of pending job array.

Support taking node out of FUTURE state with "scontrol reconfig" command.
Previous logic would keep node in FUTURE state if that was the original
configuration when slurmctld started. If job was running on the node,
it will stay running, but the node make not be visible.

Previous logic would create a environment and script file for each
  task of a job array (hard link to original actually). Due to
  file system limitations and clutter, this was less than ideal.
  This patch eliminates the redundant files, using only the original
  file created for the job array. This should also make support for
  burst buffers easier in the future for job arrays.

Make SLURM_ARRAY_TASK_MIN, SLURM_ARRAY_TASK_MAX, and SLURM_ARRAY_TASK_STEP
    environment variables available to PrologSlurmctld and EpilogSlurmctld.

We needed to send a finish from each node in the step whether it had
any activity or not.  This way the controller knew things were done
on the node and the data was sent to the database.

Burst_buffer/cray: Don't stall scheduling of other jobs while a stage-in
    is in progress.

Fix to purge terminated jobs with burst buffer errors.
bug 2123

The prolog_running counter can now exceed 1. New logic raises limit
from 1 to 4 before preventing job recovery on restart.

Added burst_buffer.conf flag parameter of "TeardownFailure" which will
    teardown and remove a burst buffer after failed stage-in or stage-out.
    By default, the buffer will be preserved for analysis and manual teardown.

What was happening was the calculation wasn't happening for memory
or nodes, just cpus and gres.

The "dw_wlm_cli paths" command returns an error if no #DW options.

bug 2087

Fix creation of advanced reservation of cores on nodes which are DOWN.
There seems to be a bug with reservations using a node list (e.g.
Nodes=something + CoreCnt=something).  The result is a reservation made that's
arguably broken; listing the reservation (scontrol show reservation) will show
"Nodes=" (blank) and "CoreCnt=0".

It's very easy to reproduce, just by doing the following against a node in a
DOWN (also tested with POWER_UP) state:
scontrol create ReservationName=tmp_res StartTime=now EndTime=now+600
Nodes=<some_non_idle_node> CoreCnt=1 Users=<some_valid_user>
scontrol show reservation.

submit_time.  0 means the job isn't eligible yet so we need to treat it so.

PrologFlags work: Setting a flag of "Contain" implicitly sets the "Alloc"
    flag. Fix code path which could prevent execution of the Prolog when the
    "Alloc" or "Contain" flag were set.
bug 2074

If a user tries to create/destroy a persistent burst buffer and
  that is disabled (the default), return a permission denied error
  rather than an invalid request error.
