Bug 6718.

With schedulerparameters=defer and prolog scripts and/or spank plugins
that take some time, jobs weren't starting within 2 seconds that tests
2.18 and 2.19 expected, causing these tests to fail.

Bug 6670.

IMO, the test as is currently designed is not representative of
an actual rpmbuild against a production released tarball, and thus
should not be relied on. Using --nodeps masks a lot of potential
errors with the spec file.

It has been disabled on Ubuntu systems for months, broken on master
for longer, and thus I am discarding it now.

This is helpful when running multiple versions against the same build.

i.e.
globals.snowflake
globals.knc
...

Not all Linux systems have a time binary, use bash instead since it has
time built in and is already required for test units.

Bug  6503.

Logs are produced by regression.py, and should not be checked in.

Update slurm.spec and slurm.spec-legacy as well.

Commit 750cc23e changed the signature for slurm_xmalloc, which
needs to be mirrored here in slurm-perl.h.

Force intermediate values to uint64_t to catch the potential overflow.

This matches the functionality in code.

Bug 5726

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.

Bug 5231

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.
