Remove FREE_NULL calls.

added definition of PROJECT... These are steps to get make rpm to work.

good base to build upon.  I'm not exacty sure if the packages that will be
built are right, but we can combine them and change thier names easily.

typo in comment. add FREE_NULL function.

srun has changed message with executable program name on launch and reattach.

get forwarded from slurmctld to every slurmd daemon.

Slurmd now accepts reconfig RPC.

   can be waited on in shutdown.

Slurmctld treats prolog failure (reported as error code in node_registration
  RPC) as sign to set node DOWN.
Slurmd reports prolog failure on srun step task launch back to slurmctld
  to set node down.

Slurmctld treats prolog failure (reported as error code in node_registration
  RPC) as sign to set node DOWN.

   (probably just an srun detaching)
 o srun: disable stdin reading if in background
         enable proper termination in attach mode

allocation is release only upon termination of the last step.

   - fix some EXTRA_DIST declarations so that CVS/ directories don't get
     inlcuded in a make dist
   - add forced target to rebuild any dependent convenience or api libs
     (if necessary)

ALLOCATED to IDLE.
Save creds to file on each cred revoke and on slurmd shutdown.

ALLOCATED to IDLE

slurmctld accepts step kill RPC and forwards the signals to slurmd(s).
slurmd processes SIGKILL, SIGSTOP, and SIGCONT via  shm_signal_step(),
all others use killpg(). All signals used to go through killpg(), which
could kill the step specific slurmd and hose the job.

slurmctld accepts step kill RPC and forwards the signals to slurmd(s).

 o Try harder to clean up shm semaphore in slurmd
 o call daemon(1,0) instead of daemon(0,0) in slurmctld to preserve chdir()

 o Only terminate IO thread if IO is done or job is in FORCETERM state

   (may be a residual from cbuf operations)
