Comments do the explaining.
* Fix deadlock in sqlite mode
Caused by starting a writer whilst within a writer
* Only complain about invalid state deltas for non-overwrite events
* Do not re-process outlier unnecessarily
* Add KindOld
* Don't process latest events/memberships for old events

* Resolve state
* Comments
* Deep forward extremity calculation

* Fix current state upsert in sync API
* Send auth events as outliers, state events as rewrite
* Sync API don't consume state events
* Process events actually
* Improve outlier check
* Fix local room check
* Remove extra room check, it seems to break the whole damn world
* Fix federated join check
* Fix nil pointer exception
* Better comments on DeduplicateStateEntries
* Reflow forced federated joins
* Don't force federated join for possibly even local invites
* Comment SendEventWithState better
* Rewrite room state in sync API storage
* Add TODO
* Clean up all room data when receiving create event
* Don't generate output events for rewrites, but instead notify that state is rewritten on the final new event
* Rename to PurgeRoom
* Exclude backfilled messages from /sync
* Split out rewriting state from updating state from state res

* Add Queryer and use embedded structs
* Add Inputer and factor out more RS API stuff
This neatly splits up the RS API based on the functionality it provides,
whilst providing a useful place for code sharing via the `helpers` package.
