Stop treating "nobody" as the error condition.

Bug 7845.

Update slurm.spec and slurm.spec-legacy as well.

If this failed, the step would launch as root instead of the desired
user, which could be exploited.

Encourage the use for restricted permissions for slurmdbd.conf since
this file will contain your MySQL username and password on most systems.

Bug 7291

In a multi-cluster environment a job may submit more jobs as part of
its workflow. This fixes situations where the variable is inherited
incorrectly on sub-jobs.

Bug 7998

srun waits for the prolog to finish before launching a job step.
In _is_prolog_finished(), slurmctld checks the state reason:

	if (job_ptr) {
		is_running = (job_ptr->state_reason != WAIT_PROLOG);
	}

But if the job is updated during the job prolog, then _update_job() will
change the state_reason, and then slurmctld will tell srun that the
prolog is completed even if it isn't. If srun launches a job step before
the extern sets up x11, then the job step won't have x11 information. To
fix this, don't change state_reason in _update_job() if it equals
WAIT_PROLOG.

This in turn fixes allocation requests that weren't rejected and they
should because the requested nodes didn't have a shared network.

Add <p> after <pre> tags, since <pre> breaks the previous <p>.
Add <p> and list tags where appropriate for correct spacing.
Replace < and > with escape characters in code snippets.
Fix some broken tags.

Bug 7212

Make the job name searched for by the test include `test${test_id}-`
so it does not mistake a job id as the job name.
Replace the random number with a timestamp to guarantee that there
are no repeats.
Add `-p` to the sacct arguments to accommodate the increased length
of the job name and to guarantee that the output never gets truncated.

Have the main scheduler and backfill scheduler make the reasons of
subsequent array tasks match the first array task, since they
sometimes didn't do this completely when the array was pending.

Bug 6814

It is possible there may be an infinite loop when placing tasks when
_at_tpn_limit() activates on every possible node. If that happens, then
the job can not be placed and an error will be returned instead.

Continuation of 16eb8b14

Bug 7629.

Add _at_tpn_limit() as helper to determine when a given node is over the
tasks_per_node limit and to log when then happens.

Bug 7629.

Option may be useful when running --stop-on-first-fail,
when the issue is fixed than it will allow restart from
the failed one.
