        * objc-foreach.c: Include objc-private/common.h.
        * objc/deprecated/METHOD_NULL.h: New file.
        * objc/objc-api.h: Include deprecated/METHOD_NULL.h instead of
        defining METHOD_NULL here.
        * Makefile.in (OBJC_DEPRECATED_H): Added METHOD_NULL.h.
        * Object.m ([+instancesRespondTo:]): Use (Method_t)0 instead of
        METHOD_NULL.
        ([-respondsTo:]): Same change.
        * objc/objc-api.h (method_get_imp): Converted it into a normal
        function so that we can hide the internals of struct objc_method.
        * sendmsg.c (method_get_imp): Implemented.
