[svn-r257] H5F.c:
    Added modification entry to H5F_open header.  Should have been done
    when i added the access template argument.

H5Fprivate.h:
    The hardcode setting to "define MPIO as the default IO
    when HAVE_PARALLEL is set" cause all test programs to fail since
    none of them is coded with the needed MPI_Initialize.  Change it
    back to the previous setting of using sequential I/O allows user
    to use sequential I/O by default and use MPIO only if he/she explicitely
    asks for it via access template setting.
