Expect is sometimes splitting lines on long output bufffers

  the volume of output, which seems to fix the problem

Under some conditions if an attempt to schedule the last task of

  task ID will be changed from the appropriate value to NO_VAL.

Bug 1770

Revert modification that would NOT count pthreads that are being
  throttled against the slurmctld limit. Harvard reported that
  slurmctld would spawn so many pthreads that it failed. In
  extreme environments, the slurmctld could spawn tens of
  thousands of pthreads with the modified logic.

Bug 1798

If a job can only be started by preempting other jobs, the old logic
  could report the error:
  "cons_res: sync loop not progressing, holding job #"
  due to the usable CPUs and GRES needed by the pending job not
  matching. This change prevents the error message and job hold
  when job preemption logic is being used. The error message and
  job hold still take place for job scheduling outside of preemption,
  which will match CPUs and GRES at the beginning.
bug 1750

Under some conditions the select/cons_res plugin will hold a job,
  setting it's priority to zero and reason to HELD. The logic in
  slurmctld's main scheduling loop previously kept its priority
  at zero, but changed the reason from HELD to RESOURCES. This
  change leaves the proper job state as set by the select plugin.
This may be related to bug 1750

The backfill scheduler will periodically release locks for other
  actions. If a job is held during the time that locks were released,
  that job might still have been scheduled by the backfill scheduler
  (i.e. it failed to check for a job with a priority of zero).

the execve() call to launch an application can fail due to the

Also add some cosmetic changes

bind to the interface of return of gethostname instead of any address on
the node which avoid RSIP issues in Cray systems.  This is most likely
useful in other systems as well.

Add level to switch table information logged by select plugin

Old logic could purge a job record for a job that was in
  completing state (if there was also a lot of agent threads).
  This change prevents purging job records for completing jobs.
