parjob-placement now covers full LSF-style parallel placement: task
range (-n min,max), capacity-driven partitioning, span[ptile=n],
span[hosts=1], span[block=n] and a host-count limit. bug-1931 points to
it for the full task-range behaviour.
pend-reason-push-dedup: skip pushing a job's pend reason to the
controller when it equals the last one the controller accepted.
