Do not run the Node Health Check on termination of the external
  step as this happens when the job allocation ends and the job
  NHC will be executed anyway.

instead of waiting till end of script.

This creates an empty directory, since we no longer bother
copying the job script or environment as of 28b7f853.

This partially reverts commit a309f77c.

It accidentally removed the menu function on mobile devices.

Add retry on file open fail and remove some unnecessary sleeps

** CID 175193: (FORWARD_NULL)

Theoretically we shouldn't have a job_desc_msg_t without an associated
part_record, but just in case let's harden the code.

Introduced in previous commit: 24365514.

If portions of a pack job launch fail, then release the full
  job allocation rather than having srun exit with outstanding
  job allocations.

Bug 4132

Initially job mem limits were tested at submission time through
_validate_min_mem_partition() -> _valid_pn_min_mem(), but not tested
again at scheduling time, thus leading to jobs incorrectly being scheduled
against partitions where the job exceeded their MaxMemPer* limit
(which can in turn be inherited from the system wide limit too).

NOTE: New WAIT_PN_MEM_LIMIT job_state_reason enum component added to support
this new waiting reason.

Bug 2291.

Modify step create logic so that call components of a heterogeneous job
      launched by a single srun command have the same step ID value.
