Fix Lua link order

Patch from Yuri D'Ella

Note that if a job is requeued, it's submit time is changed and the record appears
as a duplicate job with a different submit time. Patch by Bill Brophy, Bull.

Put -llua* in LIBS rather than LDFLAGS to get correct link order.
Without this the configure test for Lua fails when using GCC 4.6,
the default compiler on recent Linux distributions like Ubuntu
11.10.

Note this is an old bug. The new code keeps slurmstepd alive and it
keeps trying to send step completion message to slurmctld.

This make the same patch to select/linear as Carles Fenoy's patch to
select/cons_res plugin.

Added gres_cpus test. Without this test it could lead to the error "fatal: cons_res: sync loop not progressing" With this patch a job will be rejected if asking for unavailable configuration.

Print an error rather than setting CUDA_VISIBLE_DEVICES environment
variable to  "NoDevFiles" if no device files defined.

Patch 4f68cde5bd6b4fcf839f6694457373c81d9548ba from chaos/slurm by Don Lipari, LLNL

The change in function call order of commit e60abe43
resulted in slurmd daemons on front-end systems not registering with the
proper node name.

Backfill scheduling - Add SchedulerParameters configuration parameter of
"bf_res" to control the resolution in the backfill scheduler's data about
when jobs begin and end. Default value is 60 seconds (used to be 1 second).

Do not drain the compute or front-end node when trying to start a job
for which the UID is not found

Release locks on cray system after inventory and before backfill scheduling loop
in order to not process more jobs and avoid blocking pending RPCs for so long

Add configure option of "--without-rpath" which builds SLURM tools without
the rpath option, which will work if Munge and BlueGene libraries are in
the default library search path and make system updates easier.

This patch contains corrections for spelling errors in the code and
improvements for some man pages. Patch from Gennaro Oliva.

Patch by Stephen Trofinoff, CSCS.

Change the logging of a job step create failure due to SlurmctldProlog
running from info() to debug() since this can be due to a race condition.

Do not attempt to run HeathCheckProgram on powered down nodes. Patch from
Ramiro Alba, Centre Tecnològic de Tranferència de Calor, Spain.
