Continuation of 06582da8 (17.11.9)

Poll was timing out too quickly due to an incorrect conversion of
MessageTimeout. Added a multiplier so timeout reflects the correct
millisecond value.

Change slurmctld/controller.c's purge_thread_lock from static to
global extern, so the mutex can be used in slurmctld/job_mgr.c

slurm_cond_signal() needs to always be wrapped in the same mutex as
slurm_cond_[timed]wait(), or else there is a possibility that
slurm_cond_signal() will trigger before slurm_cond_[timed]wait()
is even listening, most likely causing a deadlock.

The backup slurmctld can end up without an agent thread if
read_slurm_conf() takes too long to complete. Forcing the agent_init()
here again ensures it is restarted if not currently running.

This was fixed upstream in c1a537db.

Fail early when the layout requirements cannot be satisfied in

The conditional for handling --overcommit was not sufficient to prevent
other option combinations from using that code path, resulting in
unexpected resource allocation behavior. Correct that to check that
overcommit is enabled.

If the dbd comes up after a job array has been submitted to the
controller, the controller calls _update_job_tres() which calls
assoc_mgr_set_tres_cnt_array() which allocates memory for the job's
tres_alloc_cnt. The job array gets scheduled, but job_array_split()
doesn't NULL out the pending job's tres_alloc_cnt, so both the array
task and the pending array job are pointing to the same memory. The
array task calls job_set_alloc_tres() which free's the running job's
tres_alloc_cnt and now the pending array job is pointing to bad memory
and when the array splits again the new array task tries to free
tres_alloc_cnt in job_set_alloc_tres() and segfaults.

MySQL permits up to 64-character database names, but Slurm was truncating
at 33-characters. If we exceed this limit, let the mysql_query fail and
give the admin a chance to sort it out, rather than truncating and then
failing to query against the un-truncated name later on.

While here correct the fatal() message.

Note that pipe2() is Linux-specific, but this whole cgroup plugin is
already Linux-specific in design, and the eventfd() call itself is
Linux-specific as well.
