/*-------------------------------------------------------------------------
 * Function:  H5D_mpio_spaces_xfer
 *
 * Purpose:  Use MPI-IO to transfer data efficiently
 *    directly between app buffer and file.
 *
 * Return:  non-negative on success, negative on failure.
 *
 * Programmer:  rky 980813
 *
 * Notes:
 *      For collective data transfer only since this would eventually call
 *      H5FD_mpio_setup to do setup to eveually call MPI_File_set_view in
 *      H5FD_mpio_read or H5FD_mpio_write.  MPI_File_set_view is a collective
 *      call.  Letting independent data transfer use this route would result in
 *      hanging.
 *
 *      The preconditions for calling this routine are located in the
 *      H5S_mpio_opt_possible() routine, which determines whether this routine
 *      can be called for a given dataset transfer.
 *
 * Modifications:
 *  rky 980918
 *  Added must_convert parameter to let caller know we can't optimize
 *  the xfer.
 *
 *  Albert Cheng, 001123
 *  Include the MPI_type freeing as part of cleanup code.
 *
 *      QAK - 2002/04/02
 *      Removed the must_convert parameter and move preconditions to
 *      H5S_mpio_opt_possible() routine
 *
 *      QAK - 2002/06/17
 *      Removed 'disp' parameter from H5FD_mpio_setup routine and use the
 *      address of the dataset in MPI_File_set_view() calls, as necessary.
 *
 *      QAK - 2002/06/18
 *      Removed 'dc_plist' parameter, since it was not used.  Also, switch to
 *      getting the 'extra_offset' setting for each selection.
