in order to free all memory (including that associated with pthread_create).

slurm_init_slurm_msg is replaced by slurm_msg_t_init and slurm_msg_t_copy.

slurm_msg_t_init COMPLETELY initializes the structure, so it needs to be
called BEFORE setting any variables within the structure.

It is not clear if slurm_msg_t_copy is even necessary, it is only used
in three places.

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.

actually ping if last response >SlurmdTimeout/2 ago.

for consistency across slurm

No changes in logic.

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").

conflict with global #define values.

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