MappingNotify is actually a non-optional event; it's sent to all clients
whether they want it or not.  

However it looks like qt4 already gets this right: it calls
XRefreshKeyboardMapping when it gets MappingNotify, and then calls
QKeyMapper::changeKeyboard() to update its internal state.  So you
should probably use the QKeyMapper API instead.
