Overview

Bolt 4.4. Adds impersonation (imp_user on RUN/BEGIN/ROUTE) and changes ROUTE's third field from a bare database string to a {db, imp_user} map. Descends from V43 so it inherits the "utc" patch capability; every 5.x handler descends from this class, so they inherit impersonation, the ROUTE map form, and (until V5 turns it off) the patch.
