mark private methods as hidden

We are the only possible users of private methods, so we are also the
only users who can potentially export them via using them in inline
methods. The point is: We don't need these symbols exported if we don't
do this, so marking them as hidden removes some methods from the API
without breaking anything as nobody could have used them.
