If a batch job launch request can not be built (the script file
is missing, a credential can not be created, or the user does
not exist on the selected compute node), then cancel the job
in a graceful fashion. Previously, the bad RPC would be sent to
the compute node and that node DRAINED.

Correct SelectTypeParameters=CR_LLN with job selecition of specific nodes.
Previous logic would in most instances allocate resources on all nodes
to the job.

Correct squeue's job node and CPU counts for requeued jobs.
Previously, when a job was requeued, its CPU count reported
was that of the previous execution. When combined with the
--ntasks-per-node option, squeue would compute the expected
node count. If the --exclusive option is also used, the node
count reported by squeue could be off by a large margin (e.g.
"sbatch --exclusive --ntasks-per-node=1 -N1 .." on requeue
would use the number of CPUs on the allocated node to recompute
the expected node count).

jobacct_gather/cgroup.

Support SLURM_CONF path which does not have "slurm.conf" as the file name.
bug 803

If a job has non-responding node, retry job step create rather than
returning with DOWN node error.

Add force option to all file removals ("rm ..." to "rm -f ...").
bug 673

Completing nodes is removed when calling _try_sched() for a job, which
is the case in select_nodes(). If _try_sched() thinks the job can run
now but select_nodes() returns ESLURM_NODES_BUSY, the backfill loop will
be ended.

Fix sinfo -R to print each down/drained node once, rather than once per
partition. This was broken in the sinfo change to process each partition's
information in a separate pthread.

Conflicts:
	src/sinfo/sort.c

Correct sinfo --sort fields to match documentation: E => Reason,
H -> Reason Time (new), R -> Partition Name, u/U -> Reason user (new)

it turns out SLES 11 SP3 (at least) defines it with a newline, so
this will be a problem for anyone building RPMs on that OS.

Without this patch, jobs with an infinite time limit would have
their preemption GraceTime ignored.

For the salloc, sbatch and srun commands, report usage of the
--signal option when the user requests command help.

commit 8ddadea5 combined all
pending jobs, even if they had the special exit flag set. This
treats pending and special_exit state jobs differently. Only those
jobs with state pending (and NOT special_exit) are combined in
squeue.
