* Update gomatixserverlib * Try to build invite stripped state if not given to us * SendInvite improvements * Transpose invite_room_state into invite_state.events for sync API * Remove syncapi debugging output * Use RespInviteV2 * Update gomatrixserverlib * Send the invite event as a normal roomserver event too, for incorporating into room (should this be done by the roomserver automatically for invite inputs?) * Federation sender use invite_room_state, room server try to insert membership state * Check supported room versions on the invite endpoint * Prevent roomserver query API from trying to handle requests for stub rooms * Adding a nolint * Replace IsRoomStub with RoomNIDExcludingStubs, fix query API to use that instead * Review comments
