Created new fields in job structure, then exported by jobcomp plugin to generate more information about scheduling

MAX_RANGE for maximum number of nodes increased, backfill and normal scheduler statistics, in swf2trace number of tasks equals number of requested CPUs

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

Bug 8084.

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.

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> and list tags where appropriate for correct spacing.
Replace < and > with escape characters in code snippets.
