re-arrange some job_update code so that a job's required nodes and partition can both be changed in a 
single RPC. The previous code modified the partition first and reported an error if the orignal required
nodes were not in the new partition.

    was previously disabled since Moab stored the QOS within the Comment field.

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.

this should have no impact on a live system.

    allocate tasks in blocks of the plane size.

    dependency that can not be satisfied.

    just setting the priority to 1.

BLUEGENE - Added debug flags for compiling C++ code and also added logging to another file for the bridge

BLUEGENE - moved error codes to a slurm error code from the bridge so we can have one set that is sort of stable.
