(fhandler_base::usecount): Declare.
* fhandler.cc (fhandler_base::fhandler_base): Initialize new fields.
* fhandler_console.cc (fhandler_console::get_tty_stuff): Pass NULL to third
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.
* pinfo.cc (_pinfo::set_ctty): Accommodate new archetype methods.
* pinfo.h (_pinfo::set_ctty): Make third argument explicit.
* syscalls.cc (close_all_files): Decrement controlling tty use count before
closing all handles to allow controlling tty to be closed.  Remove previous
controlling tty considerations.
