Communications now supported directly between appliciation tasks via
    Slurm's PMI library. Srun sends single message to one task on each node
    and that forwards key-pairs to other tasks on that nodes. Old code send
    key-pairs directly to each task.
    NOTE: PMI applications must re-link with this new library.

BLUEGENE - zero out values for freeing and freed blocks when a job is being added so they don't get too large.

BLUEGENE - modifications to allow sinfo and sview (in partition mode) view the correct used nodes and nodes in an error state on a bluegene system.
