when using fed_mgr_is_active(). It should only be used outside of any
locks.

Prior security check only permitted root or the SlurmUser to update.

No way to do this through sbatch, but the API would permit it.

Bug 3631.

When not in a federation, or using --local, just go directly to the
cluster without spawning a thread.

Instead of packing an empty federation rec, just pack a NULL and return
a NULL.

This introduced a race condition between RPC messages starting
to be processed ahead of the plugin init() calls completing.

This reverts commit 6e65b5cb.

Bug 3646.

Only happens in a SPANK plugin on the setenv() call.
dyn_spank_set_job_env() in unaffected, and needs the NULL value for proper
backwards-compatibility.

Bug 3503.

This should have been part of commit f84456f3

This fixes test 7.17 to work with commit a152196f

Move the working_cluster_rec reference out of the following functions:
slurm_send_recv_controller_msg(), slurm_send_recv_controller_rc_msg(),
slurm_open_controller_conn_spec() and slurm_send_only_controller_msg()
so that communcations to multiple clusters can be performed in parallel
(using threads)

If a cluster in our federation is down, it's "control_host" value
is "" and an attempt to communicate with it will abort.

Previous content has news about version 16.05 release. Updated
for version 17.02 release.

[min|max]_cpus if not already set when a job comes in.

Change slurm_load_jobs(), slurm_load_job_user() and slurm_load_job()
to all use the same underlying function, which was formerly just
used by slurm_load_jobs(). This function will get data from all
of the clusters in a federation, but in a serial fashion for now.

The clang error isn't entirely clear, but this should fix it.

the job may still point to the qos_id of the removed qos.

the job_table.  This would represent the removal of runaway jobs.

I also made it work so the versions would be easy to see.  I couldn't easily
make this into multiple commits or I would had.

Add squeue --local and --sibling options to modify filtering of jobs on
    federated clusters.

Modify slurm_load_jobs() function to load job information from all clusters
    in a federation.

Fix double free issue from commit 3851f619

Same issue from fixed in a different spot with b19637bd.
