Handle state with input event as new events (#1415)

Browse source 
* SendEventWithState events as new

* Use cumulative state IDs for final event

* Error wrapping in calculateAndSetState

* Handle overwriting same event type and state key

* Hacky way to spot historical events

* Don't exclude from sync

* Don't generate output events when rewriting forward extremities

* Update output event check

* Historical output events

* Define output room event type

* Notify key changes on state

* Don't send our membership event twice

* Deduplicate state entries

* Tweaks

* Remove unnecessary nolint

* 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
