        * Makefile.in (C_SOURCE_FILES): Added protocols.c.
        * objc-private/protocols.h: New.
        * protocols.c: New.
        * init.c: Include objc-private/protocols.h.
        (__objc_exec_class): Call __objc_protocols_init on startup.
        (__objc_init_protocols): Call __objc_protocols_add_protocol.
        * objc-private/runtime.h: Use (struct objc_method_list *) instead
        of MethodList_t, and (struct objc_method *) instead of Method_t.
        * objc/deprecated/struct_objc_class.h: Define
        __objc_STRUCT_OBJC_CLASS_defined.
        * objc-private/module-abi-8.h (struct
        objc_method_description_list): New.
        (struct objc_class): Only define if
        __objc_STRUCT_OBJC_CLASS_defined is undefined.
