* 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.

Christopher Faylor ce40c6baf7 * fhandler_tty.cc (fhandler_tty_common::dup): Just copy cygheap->ctty to child
if duping the current ctty.
(fhandler_tty_common::close): Move debugging statement earlier in function.
(fhandler_tty_slave::close): Return success when closing ctty.
* syscalls.cc (close_all_files): Avoid calling fhandler_tty_slave close method
so that open_fhs will not be decremented when closing cygheap ctty.
(setsid): Ditto.
* dcrt0.cc (do_exit): Reorganize to avoid leaving a critical section active
after vfork.
* fhandler.h (fhandler_tty_slave::get_unit): Remove regparm parameter since it
can't work in a virtualized function.

Christopher Faylor da915a3aa6 * fhandler.h (fhandler_tty_slave::ttyname): Use name from pc since it is
guaranteed to be accurate.
* fhandler_tty.cc (fhandler_tty_slave::open): Increment open_fhs appropriate
when copying ctty.
(fhandler_tty_slave::close): Remove special case handling for exit_state.  Use
ctty < 0 check instead.
(fhandler_tty_common::close): Set io_handle to NULL after closing.
* syscalls.cc (close_all_files): Specifically close cygheap->ctty, if
appropriate.
