Log message:
        Sometimes exporting the address of a symbol from a module isn't
        enough for other modules to call that symbol correctly.  If
        custom data types are used for function parameters, they need to
        be known to the caller.  This change introduces the concept of
        $(prefix)/include/modules/$(modulename).h to declare those
        structures.  Also we move m4_dump_symbols from libm4 to the m4
        module to show this concept in action.
        
        * m4/m4module.h (m4_dump_symbol_data): Moved from here...
        * modules/m4.h (m4_dump_symbol_data): ...to this new file for
        exporting data structures from modules/m4.c.
        * modules/m4.c, modules/gnu.c: Include it.
        * modules/Makefile.am (pkgmodinc_HEADERS): Install it.
        * m4/m4module.h (m4_dump_symbol_CB, m4_dump_symbols): Removed
        prototypes.
        * m4/utility.c (dumpdef_cmp, m4_dump_symbol_CB, m4_dump_symbols):
        Moved from here...
        * modules/m4.c (dumpdef_cmp_CB, dump_symbol_CB, m4_dump_symbols):
        ...to here, with slight renaming.
        (m4_export_table): Prototype and add m4_dump_symbols.
        * m4/symtab.c (m4_is_symbol_value_void): Needed for an external
        definition of m4_dump_symbols.
        * m4/m4module.h (m4_is_symbol_value_void): Prototype it.
        * m4/m4private.h (m4_is_symbol_value_void): Fast macro version.
