Fix for defining a buffer and possibly not having it NULL terminated
  after a copy. Problem reported by Coverity.

If hostlist token exceeded 1024 bytes then a buffer could overflow.
  This change also eliminates a buffer copy for better performances.
  Problem reported by Coverity.

This reverts commit 749420cf.

TravisCI uses 2-cpu nodes, so this causes the test to fail
as a suitable node cannot be found.

17.02 API has been changed so that node Port parameter is now packed and
unpacked on REQUEST_NODE_INFO RPC. 'scontrol write config' is now able to
write the Port on each of the node lines in the output file. Same way,
'scontrol show node' now displays the Port parameter too. 'sinfo' is able
to display the Port through -o "%j" or the -O "port" sinfo format string.
Default --long --Node sinfo output now includes the PORT too and sinfo is
also able to sort ascending/descending by Port through -S +/-j. sinfo man
page has been update accordingly. 'sview' also displays the Port when
displaying the full node information. Update of the Port parameter is not
supported through the clients.

Bug 3240

Move STEP_FLAG to slurmctld.h so it can be used in step_mgr.c.

Remove req_node_layout, which was only used with wiki/wiki2.
This leads to removal of _get_cpu_cnt() as well.

Remove SchedulerPort, only used for communication to Moab/Maui.
Remove slurm_get_sched_port() from API.
Remove schedport from slurm_ctl_conf struct.

Plugins are deprecated and will be removed in 17.02.

Reverts most of commit 84023f27.

Searching the PATH in slurmd can fail due to root_squash'd NFS
filesystems, leading to the "wrong" program being launched.

If you'd like the performance benefit from avoiding this lookup
during each separate task launch, set SLURM_TEST_EXEC=1 instead
which will perform the lookup once within srun, which then ensures
the lookup happens under the users own environment and not that
of the slurmd.

Bug 2992.

If running burst_buffer/cray plugin on emulated Cray (NOT a real
   Cray system with Cray APIs) and the burst buffer state information
   includes information about buffers associated with jobs which
   are either completed or no longer exist (i.e. the burst buffer
   state information is old), then ignore that old state information.
   This might possibly be related to bug 3295 if their configuration
   is bad.
