Log message:
        m4_modules are no more, we use lt_dlhandles directly and let
        latest libltdl features manage the list of loaded modules.
        * acinclude.m4: Regenerated.
        * m4/ltdl.c: Updated from master copy.
        * m4/module.c: Reimplemented to take advantage of advances in
        libltdl.
        * m4/builtin.c (m4_builtin_find_by_name): Traverse loaded module
        list with lt_dlhandle_next.
        (m4_builtin_find_by_func): Ditto.
        (m4_builtin_table_install): Use lt_dlhandle.
        (m4_macro_define): Ditto.
        (m4_macro_table_install): Ditto.
        m4/module.h: Prototype new module management API.
        (m4_modules): No longer required.
        (m4_module_init_t, m4_module_finish_t): POSIX namespace
        violations, renamed to...
        (m4_module_init_func, m4_module_finish_func): ...these,
        respectively.
        (M4INIT_HANDLER): Clean way to declare init functions in modules.
        (M4FINISH_HANDLER):  And similarly for finish functions.
        * m4/system.h (_CONC): Used by M4INIT_HANDLER and M4FINISH_HANDLER
        -- Add indirection to the CONC macro so that arguments are
        correctly expanded.
        * modules/modtest.c (m4_init_module):  Replaced with M4INIT_HANDLER.
        * modules/shadow.c (m4_init_module):  Ditto.
        Due to new init function semantics, be careful to perform the
        initialisation only on first load.
        * modules/perl.c (m4_init_module):  Ditto. And Ditto.
        (m4_finish_module): Replaced with M4FINISH_HANDLER.
        Due to new finish function semantics, be careful to perform the
        finalisation only on first load.
        * m4/m4private.h (m4_module): Removed in favour of...
        (m4_module_data): ...structure without all the wrapper fields.
        Instances of this new structure are stored associated lt_dlhandles
        with lt_dlcaller_data_set().
        * m4/builtin.c (m4_builtin_define): Takes a handle argument
        instead of the old module argument.
        (m4_builtin_table_install): Ditto.
        * modules/load.c (m4_resident_module):  Removed.  This is no
        longer implemented as a magic symbol...
        * modules/m4.c (m4_resident_module): Ditto.
        * modules/load.c (M4INIT_HANDLER): ...the module init function now
        uses the ltdl api to make the module resident.
        * modules/m4.c (M4INIT_HANDLER): Ditto.
        * modules/load.c (builtin_modules): Traverse the loaded module
        list with lt_dlhandle_next.
        (builtin_load): Much simplified in light of the reimplemented
        module loader.
        * src/freeze.c (produce_module_dump):  Cleaned up and optimised in
        light of the m4/module.c rewrite.
        (produce_symbol_dump): Ditto.
        (reload_frozen_state): Ditto.
        * m4/list.c, m4/list.h: Files deleted.  No longer required.
        * m4/Makefile.am (pkginc_HEADERS): Delete list.h reference.
        (libm4_la_SOURCES): Delete list.c reference.
        * m4/m4private.h (m4_token_data):  Add a handle field.  This
        eliminates many of the searches to find the handle associated with
        various tokens that are passed between functions.
        (struct m4_symbol):  Removed the module field.  The
        module association does not belong with the symbol...
        * m4/input.c (struct m4_builtin): ...it belongs with the builtin
        that the module implementation code is from.  Added a handle
        field.
        (m4_push_macro): Add a `handle' argument.  Changed all callers.
        (init_macro_token):  Set the `handle' field for the
        m4_token_data.
        * m4/macro.c (expand_argument): Copy the new handle field during
        reassignment.
        * modules/m4.c (macro_install): Use the new handle field to
        optimise the search for the correct builtin structure, and pass
        the handle details to m4_builtin_define.
