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.

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

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.

bug 466

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

This messsage type:
Warning: Note very large processing time from schedule: usec=9467365 began=11:06:23.003
is reporting the end time as the began value

This prevents premature re-sending of job kill RPC
(e.g. "Resending TERMINATE_JOB request JobId=#")

If the default partition has shared=force, then each job is allocated
whole nodes and core reservations tests are not valid

This fixes another error in job priority calculations

The pending jobs will have their reservation info removed
bug 455

Increase maximum number of hostlist ranges from 12k to 64k and
use malloc to allocate memory rather than using the stack
bug 458

Initiate jobs pending to run in a reservation as soon as the reservation
becomes active.
Partial fix for bug 455
