XkbAddSymInterpret adds si to the list of symbol interpretations in xkb. If updateMap is True, it (re)applies the compatibility map to all of the keys on the  keyboard. If changes is non-NULL, it reports the parts of the keyboard that were affected (unless updateMap is True, not much changes). XkbAddSymInterpret returns a pointer to the actual new symbol interpretation in the list or NULL if  it failed.
