+ (cursorY): New functions.
+
+ * termhooks.h (cursorX, cursorY): Prototypes of functions on

+ of compile-time conditionals.
+ (encode_menu_string): New function.
+ (list_of_items, list_of_panes): Use it instead of ENCODE_STRING
+ the macro, since different types of frame need different encoding

+ on a TTY. Don't barf when invoked on a text-mode frame. Check

+ invoking terminal-specific menu-show functions. Call
+ tty_menu_show on text-mode frames.
+ (Fx_popup_dialog): Moved here from xmenu.c. Test frame types at
+ run time to determine which alternative to invoke; support dialogs

+
+ Do not allocate huge temporary memory areas and objects while encoding
+ for file I/O, thus reducing an enormous memory usage for large buffers.
+ See http://lists.gnu.org/archive/html/emacs-devel/2013-10/msg00180.html.

+ iteration. Use raw_destination if E_WRITE_MAX characters is encoded.
