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

Prevent a heterogeneous job allocation from including the same nodes in
      multiple components (required by MPI jobs spanning components).

These are required by OpenMPI

Modify output of "--mpi=list" to avoid duplicates for version numbers in
    mpi/pmix plugin names.

Modify sbcast command and srun's --bcast option to support heterogeneous
      jobs.
bug 4099

In srun, if only some steps are allocated and one step allocation fails,
 then delete all allocated steps.

Set SLURM_NTASKS environment variable to reflect global task count
(needed by MPI).

Set SLURM_PROCID environment variable to reflect global task rank
(needed by MPI).

bug 3217

If srun lacks application specification for some component, the next one
      specified will be used for earlier components.

This reverts commit 00a691b9.

Modify scontrol job hold/release and update to operate with heterogeneous
      job id specification (e.g. "scontrol hold 123+4").

Fix sview to avoid messages to stderr when modifying a block, partition,
    or reservation.

This will allow dell's custom syscfg to work correctly.

NOTE: Dell calls flat memory just memory.

Bug 4034

Doing so would break the current scheduling logic.

Bug 4019

truncation of core specification and not reserving the specified cores.

Fixes Coverity CID 45174 and 45175

Bug 4053

the tree.

Bug 4050

Modify launch/slurm plugin to signal all components of a pack job rather
   than just the one (modify to use a list of step context records).

If prolog is running when attempting to signal a step, then return EAGAIN
   and retry rather than simply returning SLURM_ERROR and aborting.

Fix I/O race condition on step termination for srun launching multiple
   pack job groups. Without this change application output might be
   lost and/or the srun command might hang after some tasks exit.

Would fail when trying to create the clustername file because the
StateSaveLocation path didn't exist yet.

Bug 3988

srun jobs that could start immediately and requested multiple partitions
didn't run in the highest priority partition if the highest priority
partition wasn't listed first.

It's possible that the scontrol show jobs will show the partition list
in priority order now that the job's partition list gets sorted by
priority.

Bug 4015

Bug 3956.

Add pack_job_id and pack_job_offset to accounting database.
Modified sacct to accept pack job ID specification using "#+#" notation.
Modified sstat to accept pack job ID specification using "#+#" notation.

Bug 3999

Default to 1, unless set to 0. Allow to be set to 0 even if
GroupUpdateTime was not set before.

Move down to alphabetical position in read_config.c as well.

Bug 3956.

Fix bug in selection of GRES bound to specific CPUs where the GRES count
    is 2 or more. Previous logic could allocate CPUs not available to the job.
