        * decl.c (gfc_match_end): Pick out declared submodule name from
        the composite identifier.
        * gfortran.h : Add 'submodule_name' to gfc_use_list structure.
        * module.c (gfc_match_submodule): Define submodule_name and add
        static 'submodule_name'.
        (gfc_match_submodule): Build up submodule filenames, using '@'
        as a delimiter. Store the output filename in 'submodule_name'.
        Similarly, the submodule identifier is built using '.' as an
        identifier.
        (gfc_dump_module): If current state is COMP_SUBMODULE, write
        to file 'submodule_name', using SUBMODULE_EXTENSION.
        (gfc_use_module): Similarly, use the 'submodule_name' field in
        the gfc_use_list structure and SUBMODULE_EXTENSION to read the
        implicitly used submodule files.
