Add job "reboot" option for Linux clusters. This invokes the configured
RebootProgram to reboot nodes allocated to a job before it begins execution.

Added HealthCheckNodeState option of "cycle" to cycle through the compute
nodes over the course of HealthCheckInterval rather than running all at
the same time.
bug 884

errno before each call to the API.

Add new SchedulerParameters option of build_queue_timeout to throttle how
much time can be consumed building the job queue for scheduling.

Correct Shared field in job state information seen by scontrol, sview, etc.

allocation and CR_PACK_NODES is set layout tasks appropriately.

This includes some bug fixes and enhancements to core specialization
commit e0ebb0baca8bb2722cca20dd5c541a839311c2f2

the sinfo command is parallelized for performance reasons and it
really can not be completely parallelized for some use cases.
see bug 883

Correct logic to support Power7 processor with 1 or 2 threads per core
(CPU IDs are not consecutive).
bug 891

including state, job ids and allocated nodes counter.

Provide more precise error message when job allocation can not be satisfied
(e.g. memory, disk, cpu count, etc. rather than just "node configuration
not available").
bug 836

For "scontrol --details show job" report the correct CPU_IDs when thre are
multiple threads per core (we are translating a core bitmap to CPU IDs).
This is an enhancement of commit 83d626ca
so the node table is only loaded once for the entire job table.
bug 850

If job requests --exclusive then do not use nodes which have any cores in an
advanced reservation. Also prevents case where nodes can be shared by other
jobs.

If job requests --exclusive then do not use nodes which have any cores in an
advanced reservation. Previously the job would be allocated all of the cores
outside of the advanced reservation.

Correct support for partition with Shared=YES configuration.
Previous logic would share resources for jobs by default
(i.e. if user did not explicitly request --exclusive).
bug 758

Add DebugFlag of BackfillMap. Previously a DebugFlag value of Backfill
logged information about what it was doing plus a map of expected resouce
use in the future. Now that very verbose resource use map is only logged
with a DebugFlag value of BackfillMap

decreases and total is less than in use.

mail messages for job array events print now use the job ID using the
format "#_# (#)" rather than just the internal job ID.

Cray/ALPS system - Enable backup controller to run outside of the Cray to
accept new job submissions and most other operations on the pending jobs.

Add child_forked() function to the slurm_acct_gather_profile plugin to
close open files, leaving application with no extra open file descriptors.

it is already running.

job is JOB_COMPLETING or already pending.
