[svn-r5652] Purpose:

    Code cleanup

Description:
    Use dataset transfer property list to hold information about the MPI types
    for the current transfer, instead of setting pseudo-global variables in
    the file's struct.

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