* Missing events should be KindOld
* If we have state, use it, regardless of memberships which could be stale now
* Fetch missing state for KindOld too
* Tweak the condition again
* Clean up a bit
* Use room updater to get latest events in a race-free way
* Return the correct error
* Improve errors
It isn't really clear that the deadlines actually help in any way. Currently we can use up our 2 minutes doing something, run out of context time and then return an error which causes the transaction to rollback and forgetting everything we've done. If the message came to us from NATS then we probably will end up retrying just to be in the same situation. We'd be really a lot better if we just spent the time reconciling the problem in the first place, and then we're much less likely to need to fetch those missing auth or prev events in the future.
Also includes matrix-org/gomatrixserverlib#287 so we don't wait so long for servers that are obviously dead.
