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".

Send pack job's task IDs, node count, tasks_per_node and node_list
  from srun to slurmd as needed by MPI. This information is constructed
  by srun combining information from each individual job component's
  step information.
Set global SLURM_NODELIST, SLURM_JOB_NODELIST, SLURM_STEP_NUM_NODES,
  SLURM_TASKS_PER_NODE, SLURM_NNODES, SLURM_NTAKS and SLURM_STEP_NUM_TASKS
   for pack step.
Modify pmi2 plugin to launch a single agent for pack step rather than
   one per component.
Modify pmi2 and pmix plugins to gather global step information for
   pack steps.
Make task distribtion be configurable by step component (i.e. "block"
   on one and "cyclic" on another).

Required for pack step support

Enforce this assumption at configure time; if this is not true
there are some serious security risks that would result.

Previous commit removed this flag as part of Cygwin/Solaris cleanup.

Which then removes them from Makefile.in files after autogen.sh.

Cygwin removal previously done in ada78c4e, but the configure
script was defined.

Solaris is a dead platform; commits to remove last traces of it
will follow.

- gid instead of uid used in group_cache_lookup_job().
- needle->username is optional, and will lead to a failure
  in getgrouplist() when NULL is passed in.

Hat tip to Brian for discovering.

in salloc, sbatch, srun before process the command line options.
