[repository] refactor/cleanup entity deletion methods
* kill unused Repository.delete_info_multi (no leading _)
* kill unnecessary system_source.delete_info (almost no benefit over
delete_info_multi)
* stop giving entities list *and* extid list, gather them from
the entity when needed
* move pending eids handling into glob_delete_entities, so one can
call it directly without worrying about that
