Move code to handle multiple clusters.  Previous code could have issues
where job_db_inx space could overlap.

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.

Move the start time calculation of pending jobs into a separate pthread on Nov 3, 2010.

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.

while it is attempting to free underlying hardware is marked in error
making small blocks overlapping with the freeing block.  This only

Slurm 2.4 minor fixes

This addresses trouble ticket 85

runjob_mux

is always set when sending or receiving a message.

Set SLURM_CONF in default prolog/epilog environment instead
of only in spank prolog/epilog environment.

This change fixes a potential hang during spank prolog/epilog
execution due to the possibility of memory allocation after
fork(2) and before exec(2) when invoking slurmstepd spank
prolog|epilog.

This also has the benefit that SLURM commands used in prolog and epilog
scripts will use the correct slurm.conf file.
