[svn-r5661] Purpose:

    Code optimization

Description:
    Avoid creating MPI types (and thus requiring a MPI_File_set_view() call)
    when contiguous selections are used for dataset I/O.  This should be a
    performance improvement for those sorts of selections.

Platforms tested:
    Linux 2.2.x (eirene) w/parallel && IRIX64 6.5 (modi4) w/parallel & FORTRAN
