Jeff Squyres 427c20af0d Use a new algorithm for allgatherv. The old algorithm essentially did
N gatherv's:

  for (i = 0 ... size)
    MPI_Gatherv(..., root = i, ...)

The new algorithm simply does (effectively):

  MPI_Gatherv(..., root = 0, ...)
  MPI_Bcast(..., root = 0, ...)

This commit was SVN r12469.
