When running sacct from a federated client, the db returns jobs for each
cluster with duplicate jobs removed on each cluster. A federated job could have
ran on a different cluster when the before the jobid's rolled. This patch
filters out past old federated jobs and leaves the newest ones.

Reverted d31965 which was too slow.

This reverts commit d31965f3.

Work is incomplete, but for now we get all jobs in federation and highlight
  the local nodes associated with each job.

This is a continuation of commit 80443cc1.

Test 1.62 will fail otherwise.

Bug 3690 continuation of commit bf0429d1.

Add "cluster_name" field to node_info_t and partition_info_t data structure.
    It is filled in only when the cluster is part of a federation and
    SHOW_GLOBAL flag used.
Functions slurm_load_node() slurm_load_partitions() modified to show all
    nodes/partitions in a federation when the SHOW_GLOBAL flag is used.

bf0429d1 this is no longer needed to wait as long.

Bug 3690 continuation of commit bf0429d1.

If this failed the job was 3/4's allocated and not in the database.

This would cause a segfault if done where it happened before.

The decay thread could signal the cond before the init thread waits for
it causing deadlock.

In order to test with larger systems, modify capmc script to generate
  output with arbitrary start and end NID values

fed_mgr closes the persistent connections before they are signaled by
the persistent connection server.

Bug 3690

Document the node_features_p_node_xlate2() function and update the
  description of node_features_p_node_xlate(). These changes were
  made in commit 6690685a
bugs 3614, 3679

Allows for annotations such as
xassert(verify_lock(CONFIG_LOCK, READ_LOCK));
to ensure that the calling thread has the correct locks in
place to head off potential race conditions / corruption.

Remove outdated disclaimers, proctrack/cgroup is awesome.

(jobacct_gather/cgroup is still not recommended though.)

Change it to the default with the configurators as well.

It seems to be a popular item. It would be nice to eventually re-write
  the tool to use Slurm's perl API at some time...

Do not create a backfill resource reservation for jobs prevented
  from starting due to QOS limit.
