Remove 'si' StateInfo variable/parameter. Since st is a member of position we don't need to pass it separately as parameter. While being there also remove some line in pos_is_ok, where a copy of StateInfo was made by using default copy constructor and then verified it's correctedness by doing a memcmp. There is no point in doing that.
