Further room version wiring (#936)
* Room version 2 by default, other wiring updates, update gomatrixserverlib

* Fix nil pointer exception

* Fix some more nil pointer exceptions hopefully

* Update gomatrixserverlib

* Send all room versions when joining, not just stable ones

* Remove room version cquery

* Get room version when getting events from the roomserver database

* Reset default back to room version 2

* Don't generate event IDs unless needed

* Revert "Remove room version cquery"

This reverts commit a170d58733.

* Query room version in federation API, client API as needed

* Improvements to make_join send_join dance

* Make room server producers use headered events

* Lint tweaks

* Update gomatrixserverlib

* Versioned SendJoin

* Query room version in syncapi backfill

* Handle transaction marshalling/unmarshalling within Dendrite

* Sorta fix federation (kinda)

* whoops commit federation API too

* Use NewEventFromTrustedJSON when getting events from the database

* Update gomatrixserverlib

* Strip headers on federationapi endpoints

* Fix bug in clientapi profile room version query

* Update gomatrixserverlib

* Return more useful error if room version query doesn't find the room

* Update gomatrixserverlib

* Update gomatrixserverlib

* Maybe fix federation

* Fix formatting directive

* Update sytest whitelist and blacklist

* Temporarily disable room versions 3 and 4 until gmsl is fixed

* Fix count of EDUs in logging

* Update gomatrixserverlib

* Update gomatrixserverlib

* Update gomatrixserverlib

* Rely on EventBuilder in gmsl to generate the event IDs for us

* Some review comments fixed

* Move function out of common and into gmsl

* Comment in federationsender destinationqueue

* Update gomatrixserverlib
