Update daemon core file location documenation and modify slurmdbd and
slurmctld code to use original working directory if -D (foreground)
option used. Based upon patch from Don Albert, Bull.

There is a delay in slurmstepd that prevents jobs with many nodes
from sending step completion messages at the same time to the srun
command which is not needed on front end systems (bluegene or cray).
This has been removed and should improve performance.

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.

This prevents the problem where a daemon does chdir() then setuid()
resulting in a working directory that it can not write a core file to.

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

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

put in a clean state when a block is freed.
