Improve selection of jobs to preempt when there are multiple partitions
    with jobs subject to preemption.
bug 3824

Prevent segfault from pointer dereference to the QOS that is
being deleted.

Fix to commit 3e8aa451.

When not using a nodefeatureplugin the new feature string should just be
duplicated and returned.

Continuation of 6690685a

Usage changed

For some reason the free of resv_name and resv_ports was removed
  from master

When a federated cluster reads job state it should only restore the
job_id_sequence from jobs that originated from it and not from remote
clusters.

Routes request to origin and then to the cluster running the job.

Should be fed1,2,3 and not fed1,2,2

The glibc version does not double-fork like Slurm's version.
Rename to xdaemon to avoid confusion and ensure no one tries to
remove it again without further investigation
(see commits 6f45a2bf/954288ad).

While here, simplify it as the arguements are unchanged in the three
calling locations.

Remove incorrect documentation as well - our xdaemon() call does
not close everything.

Our local implementation was being used instead of glibc,
and does have one subtle difference - it double forks(),
whereas glibc single-forks, leading to some slight differences
in process control behavior. Revert this and take a different
approach.

This reverts commit 6f45a2bf.

Fix regression from commit c05dcb8a (bug 1923) that doesn't take
into consideration a blank char * as a valid option.

This fixes the scenario like

sacctmgr list associations user=''

which would only print account associations.

a good return code.

This also fixes the situation where the step was ending but not yet ended
so it sends the KILL_TASK_FAILED error instead of JOB_NOTRUNNING.

Also it removes the abort in favor of exit which it should had been anyways.

list_for_each)

which the backfill test window expands. This can be used on a system with
a modest number of running jobs (hundreds of jobs) to help prevent expected
start times of pending jobs to get pushed forward in time. On systems with
large numbers of running jobs, performance of the backfill scheduler will
suffer and fewer jobs will be evaluated.
