it's job steps that lack switch windows. Needed for LSF operation.
    Based upon slurm.hp.node_fail.patch.

sview grid added for most everything with some view changes and tooltips added step node_inx added for getting which nodes are in a step

slurm_init_slurm_msg is replaced by slurm_msg_t_init and slurm_msg_t_copy.

slurm_msg_t_init COMPLETELY initializes the structure, so it needs to be
called BEFORE setting any variables within the structure.

It is not clear if slurm_msg_t_copy is even necessary, it is only used
in three places.

made step_spec->overcommit 0 out cpu_count when creating a step so we don't check for avaliable processors. making it overcommit

Rely upon slurmd and srun to tell us of the step's completion.

ESLURM_TASKDIST_REQUIRES_OVERCOMMIT.

Fix but in new env.c code.

altered the resource allocation and job_step_create_response structures.  Also altered the step_layout structure

Make NO_VAL for relative mean don't-use-relative offset.

removed task dist from srun put into slurmctld.  need to remove the addresses from job allocation since that isn't needed anymore.  need to fix some issues with the way sbcast does things now which should be easy.  The switch plugins can change also since we have the tasks laid out already now before we set up the switch.  Some more clean up also will be nice in srun.

- SlurmdPidFile, SlurmdLogFile, and SlurmdSpoolDir may each contain a
  "%h" and/or a "%n", which will be replaced by the hostname or NodeName,
  respectively.
- Add new xstring.c xstrsubstitute() function.
- launch_tasks_response_msg_t structure now contains a task_ids array
- Remove SLURM_DIST_UNKNOWN from enum task_dist_states
- job_desc_msg_t now lists a seperate addresses for the 
  RESPONSE_RESOURCE_ALLOCATION message.
- Expand the job step context concept used previously for task "spawn"
  for poe.  The step context is now also used for nomal step launch.
  New SLURM API function slurm_step_launch() and associated support
  functions.
- Fix spaghetti header #includes relating to global_srun.[ch]
- Fix slurmctld segfault when slaunch --relative is used
