[svn-r21551] Maintenance: Addressed HDFFV-915 - investigate if H5open and H5close are needed in the corresponding

             Fortran wrappers.

Solutions:   The calls were not needed and were removed from the C stubs h5open_c and h5close_c for the correspnding 
             Fortran subroutines h5open_f and h5close_f.

Platforms tested: jam with gcc and gfortran, PGI and Intel
                  koala with PGI and Intel
                  linew with the standard Sun compilers
