API to query modifier set required to type a keysym

The new API is useful to implement features like auto-type and
desktop automation. Since the inputs for these features is usually
specified in terms of the symbols that need to be typed, the
implementation needs to be able to invert the keycode->keysym
transformation and produce a sequence of keycodes that can be used
to type the requested character(s).
