argument of set_ctty.
* fhandler_tty.cc (fhandler_tty_slave::open): Accommodate new archetype method
to create only one instance of a tty.
(fhandler_tty_slave::close): Don't close handles unless archetype usecount is
zero.  When that happens, close archetype too.
(fhandler_tty_slave::dup): Just copy archetype.  Set use count appropriately.
Set ctty, if appropriate.
(fhandler_tty_common::dup): Remove slave considerations.
(fhandler_tty_common::set_close_on_exec): Remove cygheap->ctty considerations.
