There are out of memory conditions where spikes of memory usage hit the
limit set. When this happens (failcnt > 0), the Kernel might be able
to reclaim unused pages and the process can continue without oom-killer
actually killing the process. This may or may not result in an app
problem, thus we want to better clarify the message.

A separate bug will track the potential addition of a new feature to
better discern memory limits being hit from oom-killer actually killing
the process. There are mechanisms to register a notifier through the
cgroup.event_control control file, so that the application can be
notified through eventfd when OOM-Killer actually kills the process.

Bug 4564

_run_prog() executes after a fork(), if some thread in the parent
was holding slurm_conf_lock() it would never be released, and the
child will deadlocked.

Already fixed for 17.11 by commit e205eeaf, this backports just
the change for _run_prog().

Bug 4562.

The ability to enforce strict content-type checking has existed since
Elasticsearch 5.3 via the http.content_type.required configuration setting.
In 5.x it is optional, and defaults to false, in Elasticsearch 6.0, that
setting defaults to true, and there is no way to disable it.

If required and not appended, Elasticsearch would response with status 406,
so "Content-Type: application/json" is appended from now on. Tested against
Elasticsearch 5.5.1 and 6.1.1.

Bug reported to slurm-users list from E.S. Rosenberg. Patch suggested didn't
check the return code of curl_slist_append() and didn't free the slist.

Bug 4478

We decided to not do this by default for the slurmd.  See bug 4478 for
more info/reasoning.

We also didn't want to rely on #include <linux/oom.h> since that might
not exist everywhere.

Format for inserted X11 cookies is now hostname/unix:display, rather
than localhost:display. This seems to resolve some issues for different
setups while not causing any issues in my test environments. This also
helps avoid a conflict between multiple nodes in a larger job if the
same display number is allocated on multiple nodes simultaneously.

Bug 4541

The slurm and pmix RPMs both attempt to install a libpmi. While Slurm's
version should be preferred, the best way to handle this is to have both
pmix and slurm packages split this off into a separate RPM that can
conflict with each other, giving the admin a way to resolve the conflict
manually.

Bug 4511.

The cluster name could have been free'd before it would be strdup'ed.
Happens when a federated persisent connection is established and the
cluster needs to sync up with the remote cluster.

Bug 4503

Remove the origin job when a remote sibling job was cancelled while the
origin was down.

e.g.
job originated on cluster1
job runs on cluster2
cluster1 goes down
job is cancelled on cluster2
cluster1 comes backup. The origin job should be removed if the sibling
job was cancelled.

Replace some references to "pack job" with "heterogenous job".
