ReadyForQuery is special in auth and simple query flows, where it _does_ signal the final confirmation of the result, but in all other flows other, more specific messages do that. Now, asyncpg will use the rules of a particular subprotocol when determining the timing of the result waiter wakeup. These changes also make most cases of Sync emission unnecessary, although that cleanup will be addressed in subsequent commits. This consolidation also results in a nice reduction of duplicated code.
