Creator and usergroups for pages linked from a given page

Creators and their usergroups (if administrator and/or autoreviewer) of every page linked from [[User:Uanfala/dab/missing-new-articles01]].

For [[w:en:WP:VPT#Fetch article creators from a list of articles]] circa 24 Feb 2019.

Gratuitous useless technobabble: finding the first revision of a given page with this method - revisions with no parent - is fast but not 100% reliable; it'll get false positives on a page that's been history merged and false negatives on a page that's been history split, and even more rarely from other weird situations. Specifically looking for the earliest revision, as in query 19060 (the r2.rev_id subquery) is slower but more reliable.
