a job or step receives a TERM or KILL signal

Added new macro SLURM_VERSION for use in autoconf scripts to determine current version of slurm installed on system when building against the api.

   a slurm.conf variable (PriorityCalcPeriod)

    the spank_job_env functionality.
 -- Improve spank_job_env interface and documentation
 -- Add ESPANK_NOT_LOCAL error code to spank_err_t

   preferred alternative to the "scontrol setdebug" command.

BLUEGENE - made it so when removing a block in an error state the nodes in the block are set correctly in accounting as not in error.

   builtin scheduler.

moved socket_accept and socket_readable functions into a common place for all the calls since the code was very similar.

   in sattach.c, step_launch.c, and allocate_msg.c

job_desc_msg_t - in, out, err have been changed to std_in, std_out, and std_err respectfully.  Needed for PySLURM, since Python sees (in) as a keyword.

Patch from Aaron Knister and Mark Grondona, to parse correctly quoted #SBATCH options in a batch script.

Accounting - Slurmctld and slurmdbd will now set uids of users which were created after the start of the daemons on reconfig.  Slurmdbd will attempt to set previously non-existant uids every hour.

-- Removed the srun -d option; must use srun --slurmd-debug instead

   after a running prolog has finished.
