Only do if job reboot requested

Including setting of default MCDRAM and NUMA modes

When the slurmctld is in background mode, it will issue double
  free calls on the incomming message buffers, likely leading
  an abort.

If an invalid trigger message is received by slurmctld, it could
  result in a non-zero array counter and a NULL element array.
  If the element array is NULL, then clear the counter to avoid
  xfree calls of bad pointers.

Do not automatically relocate an advanced reservation for individual cores
    that spans multiple nodes when nodes in that reservation go down (e.g.
    a 1 core reservation on node "tux1" will be moved if node "tux1" goes
    down, but a reservation containing 2 cores on node "tux1" and 3 cores on
    "tux2" will not be moved node "tux1" goes down). Advanced reservations for
    whole nodes will be moved by default for down nodes.

happens to matching that of the desired command. bug 2392.

Allow an existing reservation with running jobs to be modified without

a continuation to commit 87d9370f

This enables node power save logic to be used in conjunction with
  node reboot (e.g. "sbatch --reboot ...")

if data is null, we return early from the function 8 lines
earlier. coverity 44794.

Coverity doesn't like the logically-dead block now that
SLURM_MIN_PROTOCOL_VERSION has been moved forward to 14.11.

no way for this check to fail, if null we wouldn't be in the loop
body to begin with. coverity issue 44804

remove macros and replace with direct do {} while (0) blocks
as is done throughout the rest of the codebase

This commit addresses some synchronization issues with respect to
  nodes powering up or rebooting.

Add slurmd "-b" option to report node rebooted at daemon start time. Used
    for testing purposes.

Remove obsolete packaging format. Project is dead, website no
longer resolves, and if the package depends on slurm-switch-elan
that's a good sign it hasn't worked for a long time.

Remove obsolete SVN $Id$ tags from top level and src/{api,common}.

reduce reliance on fixed-sized buffers for output, helps reduce
warnings from coverity et al.

split up key/value pairs in preparation for JSON output work.
xstrfmtcat exists and is cleaner than snprintf followed by xstrcat.

use a consistent line ending rather than repeat conditional block.

output format should be unchanged, and has been tested to match
on common cases and passes all relevant regression tests.

Warning flag -Wempty-body in clang-3.7 now errors on this, split
macro definition up over multiple lines to silence.

Both the original logic and modified logic failed to lock the job
data structure prior to decrementing "prolog_running" counter.
