While we write data to this parameter, it's not really a return parameter, we after all do not fully set it, we just fill in some fields. Hence it must be initialized beforehand. According to our coding style only parameters that are purely used for returning something should be named "ret_xyz", hence this one should not be. (We'll later rely on the current behaviour that it leaves array entries for which we find no sections untouched, hence leave behaviour as is, just rename the parameters to something more appropriate). (Since we are dropping the "ret_" prefix of "ret_sections", let's rename the old "section" parameter at the same time to "section_names", to make clearer what it is about).
