This adds support for burst buffer re-issue of pre-load operation
when slurmctld restarts with job in configuring state. Also copy
NEWS item to v16.05.

Prevent job stuck in configuring state if slurmctld daemon restarted while

Valgrind's drd tool reported a race condition on a variable, so
mutex was added to wrap it. The chances of this causing a problem
are nill, but this makes it zero.

This modifies code added in Slurm version 16.05 so that it works
properly with a change made in version 15.08 with respect to the
definition of SLURMSTEPD_MEMCHECK, see commit

Previous logic could hang the slurmstepd in an infinite loop

slurmctld could die if a job existed in completing state with an invalid/defunct
partition name and "scontrol reconfigure" is run.

Make sure that /proc/#/stat file is NULL terminated to avoid
having sscan() go off the end of a buffer.
bug 2234

I've created this patch which we're using in-house to allow snc4+cache and reject other snc4 combinations.

Fix for tracking job resource allocation when slurmctld is reconfigured
    while Cray Node Health Check (NHC) is running. Previous logic would fail to
    record the job's allocation then perform release operation upon NHC
    completeion, resulting in underflow error messages.
bug 2353

While here, mark options const, and add leading underscore to denote this
as a static function (only called within hostlist.c). Also change strcmp
to xstrcmp.

Commit a6ffef22 changed this function and would alter the input hn,
which led to subsequent calls to the function having wrong prefix
lengths for that hostrange precluding it from matching correctly.

Bug 2558.
