Modify slurmctld logic to send SRUN_REQUEST_SUSPEND so that it does not wait
for a reply from salloc or srun.

This initializes the job_suspend callback function in srun.

Improve efficiency of select/linear plugin with topology/tree plugin
configured, Patch by Andriy Grytsenko (Massive Solutions Limited).

Modify smap and sview to display all nodes even if multiple
nodes exist at each coordinate.

Modify NODES_PER_COORDINATE as desired in
src/plugins/select/cray/libemulate/alps_emulate.c b/src/plugins/select/cray/libemulate/alps_emulate.c

this is a resubmission of https://github.com/chaos/slurm/pull/24

Cray systems: Add support to suspend/resume salloc command to insure that
aprun does not get initiated when the job is suspended.

Eliminate memory leak if cray.conf file is not found
Eliminate assert due to not using xmalloc if cray.conf file is found

Jimmy Tang:
- add underscores to internal helper functions
- remove static definitions of some variables
- use xfree and xmalloc when available

Peter Vermeulen
- Remove unneeded prototypes and dead code

updated drop-in replacement of the contribs/cray libalps test programs.
 * up-to-date updates of libalps (in synch with slurm's libalps)
 * support for Accelerators
 * alps_tests/reassemble_inventory and
 * alps_tests/test_reservation now have accelerator support
 * the latter implements the key/value format for passing parameters
   to e.g. the gres/gpu plugin (but here it is just a dumb test program).
Patch from Gerrit Renker and Stphen Trofinoff, CSCS.

With regard to forthcoming Accelerator support in Basil 1.2/Alps 4.0, this adds
interface support for passing the following Accelerator parameters:
 * accelerator type (currently only "GPU" is supported),
 * model/rank information (uninterpreted "family" string),
 * amount of on-board memory in MB.

Patch from Gerrit Renker and Stephen Trofinoff, CSCS.

This adds support to parse Basil 1.2/Alps 4.0 per-node accelerator information.

NOTE: THERE HAS BEEN A NEW FIELD ADDED TO THE CONFIGURATION RESPONSE RPC
    AS SHOWN BY "SCONTROL SHOW CONFIG". THIS FUNCTION WILL ONLY WORK WHEN THE
    SERVER AND CLIENT ARE BOTH RUNNING SLURM VERSION 2.3.0.pre6

Improve variable names, comments, variable types and various cosmetic
changes in select/linear.  Patch from Andriy Grytsenko (Massive
Solutions Limited).

Fix bug in layout of job step with --nodelist option plus node count. Old
code could allocate too few nodes by double counting some nodes.

changes

it happen correctly on an L/P system

the block

One when select/cray plugin is loaded (for any system)
One when "scontrol show topology" is executed (leak is slurmctld daemon)

The original logic had a problem if you shrank a job and later grew it.
Nodes previously released would reappear when the job grows, but have
zero CPUs associated with them. The problem was due to the original nodes
list of a job being preserved in the job_resources data structure. The
new logic confirms that those nodes are still in the job's allocation
before rebuilding the job_resources data structure.
