I attach a patch which reworks my previous stuff, and implements the
same behaviour (as far as I can tell) for the gtkairo backend as well
as the CLX backend.

* PORT-KEYBOARD-INPUT-FOCUS, (SETF PORT-KEYBOARD-INPUT-FOCUS):
  trampoline to PORT-FRAME-KEYBOARD-INPUT-FOCUS and (SETF ...).  The
  interpretation of this operator is to set the keyboard focus on a
  per-frame basis, and not to interact with any window manager to grab
  the focus from potentially unrelated applications.

* PORT-FRAME-KEYBOARD-INPUT-FOCUS / (SETF ...): per-backend methods,
  specialized on the port, for querying and setting the frame's focus
  sheet.  Implemented in CLX (and Null) backend using
  FRAME-PROPERTIES; in gtkairo backend using gtk_window_get_focus()
  and gtk_widget_grab_focus().

* various editor gadgets: no longer do keyboard handling in
  [dis]armed-callback; handle-event methods for assigning focus.
  frame-pointer-button-press-handler method likewise for
  INTERACTOR-PANEs.

Any comments?
