In 17~, age(xid) and mxid_age(xid) were listed as deprecated. Based on the discussion that led to 48b5aa3143, this is not intentional as this could break many existing monitoring queries. Note that vacuumdb also uses both of them. In 16, both functions were listed under "Control Data Functions", which is incorrect, so let's move them to the list of functions related to transaction IDs and snapshots.
