Log message:
        Wrap lt_dlhandle in struct m4_module.
        * m4/m4module.h (includes): No longer require clients to know
        about lt_dlhandle.
        (m4_module): New opaque declaration.
        (m4_export): Delete unused type.
        (M4INIT_HANDLER, M4FINISH_HANDLER, m4_module_init_func)
        (m4_module_finish_func, m4_module_load, m4_get_module_name)
        (m4_builtin_find_by_name, m4_builtin_find_by_func): Use new
        wrapper.
        (m4_module_makeresident, m4_module_refcount): New declarations.
        * m4/m4private.h (includes): Move <ltdl.h> here.
        (m4_module): New declaration.  Simple for now, but intended for
        growth.
        (m4__module_open, m4__module_next, m4__module_find)
        (m4__symtab_remove_module_references): Use new wrapper.
        * m4/builtin.c (m4_builtin_find_by_name, m4_builtin_find_by_func):
        Likewise.
        * m4/module.c (m4_get_module_name, m4_module_import)
        (m4_module_load): Likewise.
        (install_builtin_table, install_macro_table): Likewise.  Also,
        change return type since these always returned NULL and no one
        used the result.
        (m4_module_makeresident, m4_module_refcount): New functions.
        (m4_module_unload, m4__module_next, m4__module_find): Use new
        wrapper.
        (m4__module_open): Populate new wrapper, and associate it with the
        lt_dlhandle.
        (m4__module_exit): Use new wrapper.
        (module_remove): Likewise.  Reclaim storage on last use.
        (module_close): Delete, and inline into module_remove.
        * m4/symtab.c (m4__symtab_remove_module_references): Use new
        wrapper.
        * modules/load.c (load_init): Use new API.
        * modules/m4.c (m4_export_table): Kill unused declaration.
        (m4_init): Use new API.
        * modules/shadow.c (shadow_init): Use new API.
        * src/main.c (main): Adjust callers.
        * src/freeze.c (reload_frozen_state): Likewise.
        * tests/modules.at (unload load module): New test.
