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.

Display better debug for when an admin specifies a non-existant parent account when changing parent accounts.

Added the slurm_job_cpus_used_on_node_inx() slurm_job_cpus_used_on_node() API for working with the job_resources_t structure.

   slurm.h and deleted job_info.h.

--enable-debug no longer has to be stated at configure time to have the slurmctld or slurmstepd dump core on a seg fault.

    any other processing in spank_init().  This now prevents fatal errors from
    being mistakenly treated as recoverable.

When querying database for jobs in certain state and a time period is given only jobs in that state during the period will be returned, previously if a time period was given in sacct jobs eligible to run or running would be displayed, which is still the default if no states are requested.
