[svn-r7210] Purpose:

    Refactoring code

Description:
    Refactored "IS_H5FD_MPIO || IS_H5FD_MPIPOSIX || IS_H5FD_FPHDF5" combination
of macros in many places into single IS_H5FD_MPI macro, which has the same
definition, but should be easier to maintain.

Platforms tested:
    FreeBSD 4.8 (sleipnir)
