Revert resolving old extremities as well as new
This may no longer be needed with the new state fixes and probably just burns more CPU time than is strictly necessary.
* Fix bugs related to state resolution
* Clean up `resolve-state`
* Don't panic when entries can't be found
* Ensure we have state entries for the auth events
* Revert "Ensure we have state entries for the auth events"
This reverts commit 9b13b7ed37.
* Revert "Revert "Ensure we have state entries for the auth events""
This reverts commit d86db197e3.
* Fix bug
* Try that again
* Update gomatrixserverlib
* Remove recursion from `loadAuthEvents`
* Fix flakey sytest 'Local device key changes get to remote servers'
* Debug logs
* Remove internal/test and use /test only
Remove a lot of ancient code too.
* Use FederationRoomserverAPI in more places
* Use more interfaces in federationapi; begin adding regression test
* Linting
* Add regression test
* Unbreak tests
* ALL THE LOGS
* Fix a race condition which could cause events to not be sent to servers
If a new room event which rewrites state arrives, we remove all joined hosts
then re-calculate them. This wasn't done in a transaction so for a brief period
we would have no joined hosts. During this interim, key change events which arrive
would not be sent to destination servers. This would sporadically fail on sytest.
* Unbreak new tests
* Linting
* Feed existing state into state res when calculating state from new extremities
* Remove duplicates
* Fix bug
* Sort and unique
* Update to matrix-org/gomatrixserverlib#308
* Trim the slice properly
* Update gomatrixserverlib again
* Update to matrix-org/gomatrixserverlib#308
* Add response size and requests total to internal handler
* Move MustRegister calls to New* funcs
* Move MustRegister back to init
* Init at some place, minimize changes
* Add test infrastructure code for dendrite unit/integ tests
Start re-enabling some syncapi storage tests in the process.
* Linting
* Add postgres service to unit tests
* dendrite not syncv3
* Skip test which doesn't work
* Linting
* Add `jetstream.PrepareForTests`

* 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.
