The pack_node_list may not be ordered across multiple components, which can
  cause problems for some MPI implementations. Put the pack_node_list records
  in alphabetic order and reorder pack_task_cnts pack_tids to match

Previously the accounting sometimes recorded the job, but not the
  short lived step. It is working consistently for me now.

Problem found by test1.65

Add support for specialized cores with task/affinity plugin (previously
    only supported with task/cgroup plugin).
Add "TaskPluginParam=SlurmdOffSpec" option that will prevent the Slurm
    compute node daemons (slurmd and slurmstepd) from executing on specialized
    cores.

When a job array record is split, add the new record to the
  federation job table.
bug 4033

Utility functions for new x11 forwarding implementation.

Requests the allocated port only be available to localhost.
Follow through with the locations in the API using this, which
all need to be marked as 'false'.

Grab this so we can start using it elsewhere. Rename command
from run_script to run_command (there is already a different
run_command in the slurmd/common code that lead to conflicts).

Also grab _free_script_argv while here, and make sure we can still run
the same shutdown commands the Cray plugin relied on as before.

Previously these would show as jobid and jobid.4294967295.

While here tweak the log_set_fpfx function to take in an
xmalloc'd string directly, rather than clone it again.

Replace [file exist $file_out] with [wait_for_file $file_out] so
  we not only wait for the file to appear, but for I/O to complete

Bug 4178.

SLURM_MPI_TYPE= env variable would take precedence over command line.

Debugging logic was left in place

Restores variable definitions accidentally removed

Bug 4174.

Removed by mistake in d8d41cff.

Problem was do to "go to proceed;" before setting "nodename"
   or "lpeerid".
