For a long time configure has modified the SLURM Release number
as set in META by stripping off everything before the last '.'
when building the SLURM_VERSION_STRING. This was done so that a
release number of 0.pre1 would become just 'pre1' in the version
string printed by SLURM commands. (e.g. slurm-2.3.0-0.pre1 becomes
slurm-2.3.0-pre1 in sinfo --version).

In attempting to create a new version 2.3.0-2.x of SLURM (branched
from 2.3.0-2), it was found that this method is overzealous, and
results in a version string of just "2.3.0-1" instead of the expected
"2.3.0-2.1". Since the intent of the sed command is only to remove
'0.' from prereleases, this patch makes that explicit, so that
non-prerelease versions branched of tagged SLURM releases keep the
original Release number in the version string.

Cray - Fix for srun.pl parsing to avoid adding spaces between option and
argument (e.g. "-N2" parsed properly without changing to "-N 2").

PluginDir is a path. It shouldn't be an error to have duplicate
plugins in your path. Plus, the error is not helpful because it
doesn't specify which path is not being loaded. Therefore, just
remove the error and load the first plugin in the path as expected.

The slurmctld code that processes job notify messages unecessarily

patch allows users to send notifications to their own jobs.

Many cosmetic modifications to eliminate warning message from GCC version

salloc/mpirun does not play well together with task affinity socket binding.  The following example illustrates the problem.

[sulu] (slurm) mnp> salloc -p bones-only -N1-1 -n3 --cpu_bind=socket mpirun cat /proc/self/status | grep Cpus_allowed_list
salloc: Granted job allocation 387
--------------------------------------------------------------------------
An invalid physical processor id was returned ...

The problem is that with mpirun jobs Slurm launches only a single task, regardless of the value of -n. This confuses the socket binding logic in task affinity.  The result is that task affinity binds the task to only a single cpu, instead of all the allocated cpus on the socket.  When mpi attempts to bind to any of the other allocated cpus on the socket, it gets the "invalid physical processor id" error. Note that the problem may occur even if socket binding is not explicitly requested by the user.  If task/affinity is configured and the allocated CPUs are a whole number of sockets, Slurm will use "implicit auto binding" to sockets, triggering the problem.
