* admin/merge-gnulib (GNULIB_MODULES): Add strnlen. * lib-src/etags.c (find_entries): * src/emacs.c (main): * src/nsmenu.m (parseKeyEquiv:): * src/nsterm.m (ns_xlfd_to_fontname): * src/term.c (vfatal): Prefer !*X to !strlen (X). * lib-src/etags.c (pfnote, add_regex): * lib-src/pop.c (pop_open): * lib-src/update-game-score.c (main): * lwlib/lwlib.c (lw_separator_p): * src/doprnt.c (doprnt): * src/emacs.c (main): * src/inotify.c (inotifyevent_to_event): * src/keyboard.c (menu_separator_name_p, parse_tool_bar_item): * src/sysdep.c (get_current_dir_name_or_unreachable): * src/xdisp.c (store_mode_line_string): Use strnlen to avoid unnecessary work with strlen. * lib-src/etags.c (Prolog_functions, prolog_pr) (Erlang_functions, erlang_func): Prefer ptrdiff_t to size_t when either will do. (prolog_pr, erlang_func): New arg LASTLEN, to avoid unnecessary strlen call. All callers changed. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/strnlen.c, m4/strnlen.m4: New files, copied from Gnulib. * lwlib/lwlib.c (lw_separator_p): * src/json.c (json_has_prefix): Use strncmp to avoid unecessary work with strlen + memcmp. * src/process.c (set_socket_option): Use SBYTES instead of strlen.
