Fix for configuration of "AuthType=munge" and "AuthInfo=socket=..." with
    alternate munge socket path.

Bug 2314.

Later releases have switched over to snprintf to avoid this issue, but 14.11
did not get that patch. Bug 2295.

_slurm_rpc_complete_job_allocation.

This is a rewrite of 438365ec which didn't catch the job_ptr wasn't
in a lock so the memory issue could still of existed.  This hopefully fixes
all the spots the job_ptr wasn't in the lock.

bug 1999

Don't requeue RPC going out from slurmctld to DOWN nodes (can generate
    repeating communication errors).
bug 2002

This will only happen if a PING RPC for the node is already queued
  when the decision is made to power it down, then fails to get
  a response for the ping (since the node is already down).
bug 1995

If a job's CPUs/task ratio is increased due to configured MaxMemPerCPU,
then increase it's allocated CPU count in order to enforce CPU limits.
Previous logic would increase/set the cpus_per_task as needed if a
job's --mem-per-cpu was above the configured MaxMemPerCPU, but NOT
increase the min_cpus or max_cpus varilable. This resulted in allocating
the wrong CPU count.

Bug 1938

Requeue/hold batch job launch request if job already running. This is
  possible if node went to DOWN state, but jobs remained active.
In addition, if a prolog/epilog failed DRAIN the node rather than
  setting it down, which could kill jobs that could continue to
  run.
bug 1985

Previous logic would not report termiation siganl, only exit code,
  which could be meaningless.

Bug 1984

When nodes have been allocated to a job and then released by the
  job while resizing, this patch prevents the nodes from continuing
  to appear allocated and unavailable to other jobs. Requires
  exclusive node allocation to trigger. This prevents the previously
  reported failure, but a proper fix will be quite complex and
  delayed to the next major release of Slurm (v 16.05).
bug 1851

The 2 came from the nodelist being "None assigned", which would be treated
as 2 hosts when sent into hostlist.

If user belongs to a group which has split entries in /etc/group
    search for its username in all groups.

bug 1738

Correct counting for job array limits, job count limit underflow possible
    when master cancellation of master job record.
bug 1952

Also a very minor sanity check in job_mgr.c to make sure we at least have
a task count.  This shouldn't matter, but just to be as robust as possible.

only 1 job was accounted (against MaxSubmitJob) for when an array was
submitted.
