* fhandler.cc (fhandler_base::dup): Avoid duping a handle when an fhandler has

an archetype.
* fhandler_console.cc (fhandler_console::invisible_console): Move to the top.
(fhandler_console::set_close_on_exec): Don't set close-on-exec on handle since
it's an archetype and you don't know how many things could be using it.
