[svn-r7789] Purpose:
Bug fix & code cleanups Description: Change our use of MPI derived datatypes to not create datatypes with "0-sized" lengths, which causes the LANL Q machine to hang. Also, get rid of "prefer MPI derived datatypes" environment variable since it has no advantage. Platforms tested: FreeBSD 4.9 (sleipnir) w & w/o parallel h5committest
