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

This reverts commit 6c21c441.

This is being reverted because we have been informed turning off NHC by
default is not what Cray wants.  We hope for a day when this will be
the case and Slurm can run NHC on the compute node but until that day
this is the way we will handle it.

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.

which also makes it so we can use that instead of looking at
CR_ONE_TASK_PER_CORE in the task plugin.  This makes things layout
correctly when using --ntasks-per-core which didn't work before.

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.

No functional change.

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).
bug 2409

Change some power capping message from debug3 to debug5 if powercapping
  has nothing to do.

Set a job's --test-only start time and resources functioning properly
  with node active/available feature information (i.e. use active
  features if possible and fall-back to whole nodes and available
  features, the whole node flag is needed to insure we can reboot
  the node and change its active features).

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