All languagelinks, sisterlinks, and other meta info we need to generated the sidebar and other UI elements should be placed in the ParserOutput when rendering, and cached along with it. This avoids frequent database lookups during skin rendering, and simplifies the code (e.g. usage tracking) by using a single object to transfer information from the content rendering step to the skin output step.
