RoomPorthole

Room integration.

Room's own setQueryCallback fires when a query starts and never tells you when it finished, which makes it useless for "what is blocking right now". So this wraps the open helper instead: queries and writes are timed open-to-close, bound values are recorded, and inserts and updates report what they changed.

Not covered: raw access to the underlying SQLiteDatabase that bypasses the support layer entirely. Everything Room itself issues goes through here.
