We're finally to the point of making the massive alter to the `revision` table that we've been building up to for 2.5 years now. Changes here are: * Drop `rev_text_id`, `rev_content_model`, and `rev_content_format` that MCR obsoleted. * Drop `ar_text_id`, `ar_content_model`, and `ar_content_format` that MCR obsoleted. * Replace `rev_comment` with `rev_comment_id`. * Replace `rev_user` and `rev_user_text` with `rev_actor`, plus associated index changes. Future patches will make the code changes to migrate data from `revision_actor_temp` and `revision_comment_temp` into the new `revision` columns.
