BLUEGENE - Added back a lock when creating dynamic blocks to be more thread safe on larger systems with heavy load.

Fix cosmetic sacctmgr issue where if the user you are trying to add doesn't exist in the /etc/passwd file and the account you are trying to add them to doesn't exist it would print (null) instead of the bad account name.

Fixes bug reported by Bill Brophy, Bull.

    Dennis Leepow.

    a constraint field with a count (e.g. "srun --constraint=gpu*2 -N4 a.out").

The change resulted in some cases where job steps were allocated zero
CPUs on some nodes.

CPU count that is a multiple of the plane size

    Previously may report expected start time. Do for mysql, pgsql and filetxt
    plugins in this patch.

    Previously may report expected start time.

    allocate tasks in blocks of the plane size.

    dependency that can not be satisfied.

    just setting the priority to 1.

Improve handling of job updates when using limits in accounting, and updating jobs as a non-admin user.

Clear pending job's start_time between executions of sched/backfill.

Fix for sview started on a non-bluegene system to pick colors correctly when talking to a real bluegene system.

    a full midplane on BlueGene computers. Treat cnodes as liceses which can
    be reserved and are consumed by jobs.

    Perl can not build if both are set.

    step names, and account names with an underscore to insure proper parsing.

BLUEGENE - Fix for handling extremely overloaded system on Dynamic system dealing with starting jobs on overlapping blocks.  Previous fallout was job would be requeued.  (happens very rarely)

    "%j" in the job's output or error file specification.

BLUEGENE - If using OVERLAP mode fixed issue with jobs getting denied at submit if the only option for their job was overlapping a block in error state.

    the slurmd daemon(s). This insures that tasks in the process of getting
    spawned are killed.

    having a job start that runs into the reservation when later advanced.
