 (xmenu_show): Block input here, instead in Fx_popup_menu.
 (xw_popup_dialog): New function, with X-specific bits of popup
 dialogs.
 src/xdisp.c (deep_copy_glyph_row, display_tty_menu_item): New
 functions.
 src/window.c (Fset_window_configuration): Use run-time tests of the
 frame type instead of compile-time conditionals, when menu-bar
 lines are considered.

 (w32_popup_dialog): New prototypes.
 src/w32menu.c (Fx_popup_dialog): Function deleted.
 (w32_popup_dialog): New function, with w32 specific bits of popup
 dialogs.  Block input here.
 src/w32inevt.c (w32_console_read_socket): Minor change to add
 debugging TTY events.
 src/w32fns.c (show_hourglass): If returning early because the frame
 is not a GUI frame, unblock input.
 src/w32console.c (w32con_hide_cursor, w32con_show_cursor, cursorX)
 (cursorY): New functions.
 src/termhooks.h (cursorX, cursorY): Prototypes of functions on
 WINDOWSNT, macros that call curX and curY elsewhere.
 src/termchar.h (struct tty_display_info) <showing_menu>: New flag.
 src/term.c (tty_hide_cursor, tty_show_cursor) [WINDOWSNT]: Call w32
 specific function to hide and show cursor on a text-mode terminal.

 (tty_menu_new_item_coords, tty_menu_show): New functions.
 (syms_of_term): New DEFSYMs for tty-menu-* symbols.
 src/nsterm.h (ns_popup_dialog): Adjust prototype.

 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
 of menu items.

 of, or in addition to, compile-time conditionals.
 (menu_item_width, Fmenu_bar_menu_at_x_y): New functions.
 (Fx_popup_menu): Detect when the function is called from keyboard
 on a TTY.  Don't barf when invoked on a text-mode frame.  Check
 frame type at run time, instead of compile-time conditionals for
 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
 on TTYs.

 <Qecho_keystrokes>: New static variable.
 (read_key_sequence): Accept an additional argument, a flag to

 window-system being available.
 src/editfns.c (Fmessage_box) [HAVE_MENUS]: Don't condition the call

 (restore_current_matrix): Restore margin areas.
 (update_frame_with_menu): New function.

 Add prototypes.
 src/alloc.c (make_save_ptr): Now compiled unconditionally.
