JoinChannel made the channel, counted its members, ran the join checks and inserted the member as separate statements, so two requests could each decide on a count the other was about to change: +l was exceeded, two first joiners both became operator, and a JOIN racing the last PART failed its foreign key and answered 500. db.CreateOrJoinChannel now does all of that, and uses up the invite, in one transaction; the join checks moved into it, and the service turns its refusals into the same IRC errors as before. PART and KICK remove the member and delete an empty channel in one transaction (db.PartChannelAndDeleteIfEmpty). Model: opus-5-5
