Avoid reporting more allocated CPUs than exist on a node. This can be
    triggered by resuming a previosly suspended job, resulting in
    oversubscription of CPUs.

Remove unneeded code that commit 8274ea54 fixed.

This code would 0 out all GRES/TRES on a reconfig which isn't what we want.

backport of commit 4f2e2801 from v16.05

Needed to change a couple of variables from 32- to 64-bit.

Add new burst_buffer.conf parameters: ValidateTimeout and OtherTimeout.
See man page for details.

previously take 2 restarts of the slurmdbd to make it stick correctly.

single-threaded cores.  A regression caused only 1 socket to be used on
this kind of node instead of all that were available.

If a job allocation returns some invalid contents, the pointer
  to the job structure may be NULL. This change preserves the error
  message and avoids a segv.

Fix case where if the backup slurmdbd has existing connections when it gives up control that the it would be killed.

If the backup had existing connections when giving up control, it would try to
signal the existing threads by using pthread_kill to send SIGKILL to the
threads. The problem is that SIGKILL doesn't go the thread but the main process
and the backup dbd would be killed.

This would cause the slurmctld to cache the old default which wasn't valid
and cause the user to have to request the association always.

Each node could have fewer tasks allocated on a node than the plane
  size, which broke the test. The plane size needs to be treated
  as a maximum consecutive rank value.

Create a "task" cgroup at job allocation time via the prolog container.
  A dummy "sleep" process will occupy the cgroup so long as the job exits.
