added some bgl specs back into the job_desc_msg_t so lcrm can use bgl specs for job creation.  Also changed all slurm_auth_cred's to auth_cred instead of just cred.

added initialize to a lot of places so forward_struct_init didn't get into a funky state on local vars.

to spawned tasks (based upon work by Daniel Christians, HP).

Modify set_span function to take an optional desired fanout parameter.

First patch to x_ac_debug.m4:

 "I noticed a bit ago that ./configure --enable-debug has been broken
  in SLURM for awhile -- it does not append "-Wall" to builds.
  
  This patch fixes the problem in x_ac_debug.m4."

Second patch, "fix-compile-warnings.patch", cleans up alot of warnings
revealed by the first patch.  I needed to clean up the patch because it
removed some variables and labels that were used within #ifdef sections.

New general configuration file parser and slurm.conf handling code.
Allows long lines to be continued on the next line by ending with a "\".
Whitespace is allowed between the key and "=", and between the "=" and
value.

slurm.conf is now read only once, and resulting data structures can be
shared between application and slurm library code.

WARNING: A NodeName may now occur only once in a slurm.conf file.
  If you want to temporarily make nodes DOWN in the slurm.conf,
  use the new DownNodes keyword (see "man slurm.conf").

    of SlurmdTimeout and SlurmctldTimeout for communications to slurmd and
    slurmctld daemons repsectively.

UCRL-CODE-2002-040 to UCRL-CODE-217948. No changes 
in any logic.

The slurmd build no longer includes mgr.c, task.c, slurmd_job.c, io.c,
fname.c, ulimits.c, and pdebug.c since these are only needed in the new
slurmd_step binary.

Both slurmd and slurmd_step daemons now include slurmd_step_init.c which
has the pack/unpack functions used at slurmd_step startup time.

The run_script function is moved to its own file run_script.c since both
daemons need it at the moment.  This is candidate for moving to src/common.

Broke slurmd_step.c up into functions in preparation for future code
additions.

read_proc.c does not appear to be used anywhere, so that might
be another file that could be removed from the slurmd build.

slurm.conf parameters.  This allows prolog and epilog files that srun
launches before and after a job step.

replaced by MpiDefault=mpich-gm.

    of communication protocol over IBM Federation switch.
 -- Add new slurm.conf parameter ProctrackType (process tracking) and
    associated plugin in the slurmd module.
