        Move [WebDataSource mainResource] and [WebDataSource subresources] down into WebCore
        as the push to core-ify WebArchives continues.

        This patch also introduces a behavior change.  WebCore allows ArchiveResources with null or empty data.  
        WebKit has had the inexplicable distinction of allowing empty Data in a WebResource, but not null.  
        Since WebResource is API, I decided to leave it be to avoid a behavior change.  But internally created resources 
        (as in "while archiving a page") are accepting of null or empty data.

        This actually fixes a bug where not all subframes are archived, and resulted in a layout test change.

        Updated results, as we now more consistently archive empty frames/empty resources
