[svn-r6820]

Purpose: Fortran updtae

Description: Created new functions h5pset(get)_fapl_mpiposix_f


Platforms tested: Compilation was tested with semi-manual h5committest.
                  (I ahd to built and test manullay on modi4 parallel because
                   of some weird failure of h5committest on modi4)
                  There are no tests yet for those functions. Kent was
                  going to use them in the MEAD project to test
                  the performance.
