Implement scrolling of TTY menus when the screen is too short.
src/term.c (tty_menu_display): Accept an additional argument, the
menu item from which to start displaying the menu. Account for
the value of Y when limiting the menu to the number of available
screen lines.
(mi_result): New enumeration.
(read_menu_input): Return enumerated value. When the y coordinate
hits min_y or max_y, return scroll indication instead of wrapping
around the menu.
(tty_menu_activate): Handle the scrolling indications from
read_menu_input. Compute the first menu item to display and pass
it to tty_menu_display.
lisp/menu-bar.el (tty-menu-navigation-map): Bind shifted mouse clicks
to commands that scroll the menu.
