altered the resource allocation and job_step_create_response structures.  Also altered the step_layout structure

    the code)

updated return codes from slurm_send_recv_rc_msg_only_one and slurm_send_recv_contoller_rc_msg to either 0 or -1 and added error checking to api/signal.c

call to slurm_open_controller_conn

fixed forward logic to report correct reponse for all childern and parent.  Fixed jobacct logic to always be able to work off submit time.  changed logic to in shutdown to wait around to make sure shutdown message is sent to all slurmds.

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.
