If salloc was run as interactive, with job control, reset the foreground
process group of the terminal to the process group of the parent pid before
exiting. Patch from Don Albert, Bull.

Add cray.conf parameter of SyncTimeout, maximum time to defer job
scheduling if SLURM node or job state are out of synchronization with ALPS.

One of our testers created an illegal topology.conf file.

He has a config you probably wouldn't see in production, but can see in
testing when you are sometimes given a collection of miscellaneous
resources.

          |-- nodes
switch1 --|
          |-- switch2 -- nodes

He tried the topology.conf file below. Switch s1 is defined twice. Slurm
accepted this config, but wouldn't allocate nodes from both switches to
one job.

SwitchName=s1 Nodes=xna[14-26]
SwitchName=s2 Nodes=xna[41-43]
SwitchName=s1 Switches=s2

I believe slurm shouldn't allow the second definition of switch s1. The
attached patch checks for duplicate switch names.

This change applies only to Cray systems and only when the srun
wrapper for aprun. Map --exclusive to -F exclusive and --share to
-F share. Note this does not consider the partition's Shared
configuration, so it is an imperfect mapping of options.

A node DOWN to ALPS will be marked DOWN to SLURM only after reaching
SlurmdTimeout. In the interim, the node state will be NO_RESPOND. This
change makes behavior makes SLURM handling of the node DOWN state more
consistent with ALPS. This change effects only Cray systems.

Fix the node state accounting to be consistent with the node state
set by ALPS.

Change in GRES behavior for job steps: A job step's default generic
    resource allocation will be set to that of the job. If a job step's --gres
    value is set to "none" then none of the generic resources which have been
    allocated to the job will be allocated to the job step.
Add srun environment value of SLURM_STEP_GRES to set default --gres value
    for a job step.

On Bluegene systems, smap's command-line mode would generate an invalid
