* fhandler.h (fhandler_console::send_winch_maybe): New method. 

* fhandler_console.cc (set_console_state_for_spawn): Remove if 0'ed code.
(fhandler_console::send_winch_maybe): Define new method.
(fhandler_console::read): Use send_winch_maybe where appropriate.
(fhandler_console::init): Just call all tcsetattr rather than output_tcsetattr.
* select.cc (peek_console): Reorganize so that send_winch_maybe is called for
everything but keyboard input.
