* Fixes registration of event handler for xinput-2 device changes, revealed by this improvement. * Pushes `.unwrap()` panic-ing outwards to callers. * Includes a description of what the X11 call was doing when a failure was encountered. * Fixes a variety of places where the X11 reply wasn't being inspected for failures. * Destroys windows on failure during setup. New structure makes it possible for the caller of `open_window` to carry on despite failures, and so partially initialized window should be removed (though all calls I looked at also panic currently). Considered pushing this through `linux/x11/client.rs` too but figured it'd be nice to minimize merge conflicts with #20853.
