_job_create() consistent with similar logic in select_nodes().

partition in the slurm.conf.

Change "AveVSize" to "AveVMSize" in sstat man page to match the code.
Addresses SchedMD bugzilla entry 7 by Cray.

One of our testers created an illegal topology.conf file.

He has a config you probably wouldn't see in production, but can see in
testing when you are sometimes given a collection of miscellaneous
resources.

          |-- nodes
switch1 --|
          |-- switch2 -- nodes

He tried the topology.conf file below. Switch s1 is defined twice. Slurm
accepted this config, but wouldn't allocate nodes from both switches to
one job.

SwitchName=s1 Nodes=xna[14-26]
SwitchName=s2 Nodes=xna[41-43]
SwitchName=s1 Switches=s2

I believe slurm shouldn't allow the second definition of switch s1. The
attached patch checks for duplicate switch names.
Patch from Rod Schultz, Bull.

Bug in selec/cons_res using tasks-per-node and cpus-per-task

tasks_per_node and cpus_per_task not getting proper allocation and
failing in srun with "Requested node configuration is not	available"

This reverts commit 350ef5dc.

Modify salloc, sbatch, and srun node specification parsing to accept
a number followed by a suffix of "M" to multiply the numeric value
by 1,048,576 (1024 x 1024).

Large-scale update of bluegene.conf man page to incorporate BlueGene/Q
information plus some general updates.

Major update to BlueGene web page specifically to include BlueGene/Q information.

The squeue command was printing bad I/O nodes or c-nodes information
for pending jobs. There was on midplane name, just the I/O or c-node
specification.

test8.22   Bluegene/Q only: Stress test of running many job step allocations
           within the job's allocation
test8.23   Bluegene/Q only: Test that multple jobs allocations are properly
           packed within a midplane

These changes more thouroughly test Bluegene/Q job step placement
algorithms and validate several recent bug fixes in the SLURM code.

On Bluegene/Q systems, the job step allocation needs to be larger
than requested in some cases due to the job allocation geometry
(e.g. a 5 cnode allocation needs to be scaled up to at least
6 cnodes). This enhancement fixes that logic if multiple size
increases are needed.

next parallel step is ran on a sub block, SLURM won't over
subscribe cnodes.
