Basic sync filtering (#1721)

Browse Source 
* Add some filtering (postgres only for now)

* Fix build error

* Try to use request filter

* Use default filter as a template when retrieving from the database

* Remove unused strut

* Update sytest-whitelist

* Add filtering to SelectEarlyEvents

* Fix Postgres selectEarlyEvents query

* Attempt filtering on SQLite

* Test limit, set field for limit/order in prepareWithFilters

* Remove debug logging, add comments

* Tweaks, debug logging

* Separate SQLite stream IDs

* Fix filtering in current state table

* Fix lock issues

* More tweaks

* Current state requires room ID

* Review comments
