* Put federation client functions into their own file
* Look for missing auth events in RS input
* Remove retrieveMissingAuthEvents from federation API
* Logging
* Sorta transplanted the code over
* Use event origin failing all else
* Don't get stuck on mutexes:
* Add verifier
* Don't mark state events with zero snapshot NID as not existing
* Check missing state if not an outlier before storing the event
* Reject instead of soft-fail, don't copy roominfo so much
* Use synchronous contexts, limit time to fetch missing events
* Clean up some commented out bits
* Simplify `/send` endpoint significantly
* Submit async
* Report errors on sending to RS input
* Set max payload in NATS to 16MB
* Tweak metrics
* Add `workerForRoom` for tidiness
* Try skipping unmarshalling errors for RespMissingEvents
* Track missing prev events separately to avoid calculating state when not possible
* Tweak logic around checking missing state
* Care about state when checking missing prev events
* Don't check missing state for create events
* Try that again
* Handle create events better
* Send create room events as new
* Use given event kind when sending auth/state events
* Revert "Use given event kind when sending auth/state events"
This reverts commit 089d64d271.
* Only search for missing prev events or state for new events
* Tweaks
* We only have missing prev if we don't supply state
* Room version tweaks
* Allow async inputs again
* Apply backpressure to consumers/synchronous requests to hopefully stop things being overwhelmed
* Set timeouts on roomserver input tasks (need to decide what timeout makes sense)
* Use work queue policy, deliver all on restart
* Reduce chance of duplicates being sent by NATS
* Limit the number of servers we attempt to reduce backpressure
* Some review comment fixes
* Tidy up a couple things
* Don't limit servers, randomise order using map
* Some context refactoring
* Update gmsl
* Don't resend create events
* Set stateIDs length correctly or else the roomserver thinks there are missing events when there aren't
* Exclude our own servername
* Try backing off servers
* Make excluding self behaviour optional
* Exclude self from g_m_e
* Update sytest-whitelist
* Update consumers for the roomserver output stream
* Remember to send outliers for state returned from /gme
* Make full HTTP tests less upsetti
* Remove 'If a device list update goes missing, the server resyncs on the next one' from the sytest blacklist
* Remove debugging test
* Fix blacklist again, remove unnecessary duplicate context
* Clearer contexts, don't use background in case there's something happening there
* Don't queue up events more than once in memory
* Correctly identify create events when checking for state
* Fill in gaps again in /gme code
* Remove `AuthEventIDs` from `InputRoomEvent`
* Remove stray field
