[src/trunk]: src Implement ncurses extensions is_leaveok and is_keypad.
details: https://anonhg.NetBSD.org/src/rev/80af80089b35

description:
Implement ncurses extensions is_leaveok and is_keypad.
The former allows the ncurses (and pdcurses) macros getsyx and setsyx
to be implemented, which is needed by a surprising number of applications.
The latter is needed for Python curses support so it doesn't have to dive
into ncurses window structure.
