error message.

If a reservation's nodes value is "all" then track the current nodes in the
    system, even if those nodes change. Nodes will automatically be added to
    or removed from a reservation when slurm.conf changes.

Bug 2281

Rename the variable to match rest of codebase while here. This is related to
bug 2295, although snprintf() protects against buffer overflow in 15.08 and up.

Bug 2273

Don't use lower weight nodes for job allocation when topology/tree used.
bug 2284

Preemption/gang scheduling: If a job is suspended at slurmctld restart or
    reconfiguration time, then leave it suspended rather than resume+suspend.

task/affinity: Disable core-level task binding if more CPUs required than
    available cores.
bug 2267

Improve the logging of job submit RPC contents; add descriptor/name
  to some of the fields printed rather than just raw numbers.

This is needed to properly enforce limits and account for usage.

Remove the 1024-character limit on lines in batch scripts, which was
causing long lines to be silently truncated. I noticed it when jobs were
getting created with fewer dependencies than specified.

Also increase the line length when showing job info.

No change in logic

sched/backfill: If a job can not be started within the configured
    backfill_window, set it's start time to 0 (unknown) rather than the end
    of the backfill_window.

If a pending job array has multiple reasons for being in a pending state,
    then print all reasons in a comma separated list.

Before:
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
       97354_[1-4]     debug      tmp    jette PD       0:00      1 (Resources)

After:
             JOBID PARTITION     NAME     USER ST       TIME  NODES NODELIST(REASON)
       97354_[1-4]     debug      tmp    jette PD       0:00      1 (Resources,JobHeldUser)

The tests were sometimes failing unless I gathered accounting
  data at more frequent intervals. This seems to work with default
  accounting collection intervals.
