AccountUtilizationByUser report a parent could potentially (correctly)
be larger than the sum of it's children because of the way

the =.

period.  This would only hit you if you rerolled a 15.08 prior to this
commit.

Don't expand on the format or arguments, these have changed in
16.05 already and may vary further with BB/generic support.

These are very unlikely to ever occur, but this helps harden the code.

Compare the saved clustername to slurmctld's, if there's a mismatch prevent
slurmctld from starting to avoid corruption from separate clusters attempting
to share a single state directory.

Bug 2433.

Non-GLIBC LIBC's are strict about when these functions are visible.

Bug 2427

Reproduced with:
sacctmgr show user withassoc user= user=<username>

Add new PowerParameters options of get_timeout and set_timeout. The default
    set_timeout was increased from 5 seconds to 30 seconds. Also re-read current
    power caps periodically or after any failed "set" operation.

Build should work on non-glibc distributions by better POSIX conformance.

Already had a mix of both standards, so no net change to build.

Had already fixed this in FreeBSD build, so move that outside the #ifdef

Null implies jobacct_gather/none, and slurmd should not query slurmstepd for
accounting information. Otherwise safe_read will block forever, and successive
calls will max out the thread limit and slurmd will hang.

structure.

This is technically incorrect (although usually ignored),
and will cause errors if compiling against slurm.h with -Wpedantic.

Otherwise --nice=0 is (16-bit) NO_VAL, just the same as if
--nice was not set at all. Allows for job_submit plugins to
distinguish user intent and override. Bug 2415.

qalter and qrerun have wrong end-of-line encoding: \r\n rather than \n.

To fix it, please run
sed -e 's/\r$//' -i contribs/torque/qalter.pl
sed -e 's/\r$//' -i contribs/torque/qrerun.pl

Note that these two files have different permission (644) compare to other .pl files (755).

Use PRIu64 instead of %ld for uint64_t types (libsh5util_old),
%zu instead of PRIu64 for size_t.

Add macros to fix compatibility for IPv6, deal with
lack of POLLRDHUP on FreeBSD.

Handle difference in cpu affinity APIs in gres.c.

$((10#$SLURM_API_MAJOR)) is bash-specific. replace with portable
${SLURM_API_MAJOR#0} which accomplishes the same thing.

The first forces bash to treat the value as base-10 even with a
leading zero, the second portable format strips a leading zero off.
