Raises a TypeError for non-string values.

        The only legal non-string value if we allow valueless
        options is None, so we need to check if the value is a
        string if:
        - we do not allow valueless options, or
        - we allow valueless options but the value is not None

        For compatibility reasons this method is not used in classic set()
        for RawConfigParsers. It is invoked in every case for mapping protocol
        access and in ConfigParser.set().
