In the event of a race condition on cgroup create/delete calls
in separate job steps, replace retry logic with a lock. This is
an enhancement of the retry logic recently added to version 2.6,
but the more complex logic (here) is only being added to v13.12.

This hardens the code although no such problem has been observed

Minor code enhancements to select/cons_res:
Replace loop and value set with memcpy
Eliminate redundant zero set of memory being freed

Add cgroup create retry logic in case one step is starting at the
same time as another step is ending and the logic to create
and delete cgroups overlaps.
bug 447

I did the merge improperly

If a node has GRES and multiple threads per core the select/cons_res
plugin can get stuck in an infinite loop.

If slurmd fails to get IPMI value, then I propose to force to wait 1 second instead of asking BMC again. (Part 3/4 of the patch).
If IPMI init fails when slurmd forces to update the value, then we should not update the value. (Part 4/4 of the patch
Part 1/4 and 2/4 add a security in IPMI init because the function can be call several time.
This force to return SLURM_FAILURE if the first call failed, since the other call will not do anything.

bug 469

Previously a node failure would always requeue the job

jobs submitted afternotok to run.

Restore default behavior of allocating cores to jobs on a cyclic basis
across the sockets unless SelectTypeParameters=CR_CORE_DEFAULT_DIST_BLOCK
or user specifies other distribution options.

Expect timing was sometimes causing failures

File delays sometimes larger than 60 seconds

Change Sockets to SocketsPerBoard and Procs to CPUs

If the backfill scheduler relinquishes locks and the normal job
scheduler starts a job that the backfill scheduler was actively
working, the backfill scheduler will try to re-schedule that
same job, possibly resulting in an invalid memory reference
or other badness.

Fix for --cpu_bind=map_cpu/mask_cpu/map_ldom/mask_ldom plus
--mem_bind=map_mem/mask_mem options, broken in 2.6.2.

Expect was failing periodicallly due to apparent timing problems

make sure we weren't the one holding things up.
