Brian Barrett 93a2f31932 Use a recursive halving communication algorithm similar to the one used by

MPICH2 for "small" commutative operations in the reduce_scatter basic
implementation.  "small" is currently pretty big, as it doesn't take
much to beat reduce/scatterv.  Need to do much more than this for
better all around performance of MPI_Reduce_scatter, but this was enough
to solve the problems I was having.

This commit was SVN r13348.

Complete next round of message size reduction: "strip" the descriptive info from the returned values. I have now added a flag to the gpr address mode (ORTE_GPR_STRIPPED) that instructs the gpr to not include segment names or tokens in the returned gpr_value_t objects.
