Close the batch job's environment file when it contains no data to avoid
leaking file descriptors.

This patch adds logic to work around advanced reservations better.

Change node_req field in struct job_resources from 8 to 32 bits so we can
run more than 256 jobs per node.

Using the syscalls directly rather than calling bin/(u)mount via
system() avoids a few fork + exec calls, and provides better error
handling if something goes wrong.

Users of this functionality are also updated to use slurm_strerror in
order to provide a more informative error message.

The mount and umount syscalls are Linux-specific, but so are cgroups
so no portability is lost.

I would like to make two changes to this:

1) since the reservation name can easily exceed 9 characters, I would like the field to be however large it needs to be without truncating the name. I did this by looking at the names then setting the field size to that width.

2) The other headers are in capitals, so I changed

 ResName    State       StartTime             EndTime           Duration  Nodelist

to

RESV_NAME        STATE           START_TIME            END_TIME     DURATION  NODELIST

Correct parsing of srun/sbatch input/output/error file names so that only
the name "none" is mapped to /dev/null and not any file name starting
with "none" (e.g. "none.o"). This fixes bug #98.

Gres: If a gres has a count of one and an associated file then when doing
a reconfiguration, the node's bitmap was not cleared resulting in an
underflow upon job termination or removal from scheduling matrix by the
backfill scheduler.

Cray and BlueGene - Do not treat lack of usable front-end nodes when
slurmctld deamon starts as a fatal error. Also preserve correct front-end
node for jobs when there is more than one front-end node and the slurmctld
daemon restarts.
