environment variable and indentation.

They could either be running on another cluster or not active on the
cluster.

Continuation of 3a9970c0

If a task in a parallel job fails and it was launched with the
    --kill-on-bad-exit option then terminated the remaining tasks using the
    SIGCONT, SIGTERM and SIGKILL signals rather than just sending SIGKILL.

Sinfo command with support for federated clusters

The job was completing before the test could find that the job was
running. The script was running for 10 seconds and wait_for_fed_job can
back off and check only every 10 seconds.

Can't use the revoked state to determine if the job is pending or not
since an origin job could be revoked if it doesn't have an active job on
itself.

Add slurm_load_partitions2() function to route RPC to specific cluster
Add slurm_load_node2() and slurm_load_node_single2() functions to
  route requests to specific cluster in a federation
Modify srun to get node/partition information for each cluster in a
  federation at the same time using separate pthreads
Add sinfo sort by cluster name (--sort V)

Updating after changes to show partition name.

Refactor the functions used to load state information.
  Reservation and BG block information will be local only.

Add --local option
Add %V/%cluster format option to print cluster name

If there were no clusters in the system then the dbd would insert a row
in the database and then on the next time the dbd would start (with no
clusters) it would attempt to insert the row again and fatal. Now it
always makes a query against the database and if there are no clusters
in the system, then it inserts the current db version into the table.

Without this test the macro _entity_update_kv_helper() will use a
  NULL value for oldvalue and abort

Treat the same as having the --local option and only get information
  from the identified cluster.
If sprio --cluster option is set, then implicitly set --local

Fix the sprio API so that jobs that are on remote federations only
  and in multiple partitions do not remove all but one partition's
  record. Use a hash function to turn the partition name into a
  number and insure that every unique job ID & partition name are
  reported by sprio.

If sysconf() fails, it returns -1, which was not being handled
  properly.
  Coverity CID 59941

The sort list function was flawed and there was a bug in the job
priority API used by sprio

Add sprio --local and --sibling options for use in federation of clusters.
