Option rejects user requests to shrink running jobs.

(Jobs using --no-kill may still shrink due to node failures.)

Bug 5716.

Only call to it was removed in the prior commit, and all the
interfaces returned "true" (even if they probably shouldn't have,
such as select/cray).

Add new SchedulerParameter of permit_job_expansion to permit expansion of
running jobs.

Replace the two calls to select_g_job_expand_allow() as all plugins return
true anyways at this point. Return ESLURM_NOT_SUPPORTED instead of
ESLURM_DEPENDENCY in one location as well to provide a better error
message back to the user.

is try to print a log message.  Since we are already in that lock it
will deadlock.

We document that DerivedExitCode is the highest exit code of the srun
steps, so we need to exclude the batch step. The extern step was already
excluded.

This means we can find batch steps.  NO_VAL isn't used in the code
to return the first one.

delete_step_record.

so that squeue -s and sstat will show the batch step, and sacct will
show the batch step before the job finishes.

Bug 6196.

It turns out REQUEST_STEP_COMPLETE is never sent by the batch step.

Run autogen.sh, which picked up one older uncommited change to
a comment line in contribs/perlapi/libslurmdb/Makefile.in.

The correct printf format for size_t is %zu not %lu.

This reverts commit 2707a9c0.

A lot of places rely on a zero size (or, after xcalloc conversion, count)
resulting in a NULL return, so stop xassert()'ing those cases and avoid
jumping to the unpack_error label.

Bug 6430

The code to handle it was already there, this just made it so we
actually parsed it.
