Per-room consumers (#2293)
* Roomserver input refactoring — again!

* Ensure the actor runs again

* Preserve consumer after unsubscribe

* Another sprinkling of magic

* Rename `TopicFor` to `Prefixed`

* Recreate the stream if the config is bad

* Check streams too

* Prefix subjects, preserve inboxes

* Recreate if subjects wrong

* Remove stream subject

* Reconstruct properly

* Fix mutex unlock

* Comments

* Fix tests

* Don't drop events

* Review comments

* Separate `queueInputRoomEvents` function

* Re-jig control flow a bit
