Send-to-device support (#1072)
* Groundwork for send-to-device messaging

* Update sample config

* Add unstable routing for now

* Send to device consumer in sync API

* Start the send-to-device consumer

* fix indentation in dendrite-config.yaml

* Create send-to-device database tables, other tweaks

* Add some logic for send-to-device messages, add them into sync stream

* Handle incoming send-to-device messages, count them with EDU stream pos

* Undo changes to test

* pq.Array

* Fix sync

* Logging

* Fix a couple of transaction things, fix client API

* Add send-to-device test, hopefully fix bugs

* Comments

* Refactor a bit

* Fix schema

* Fix queries

* Debug logging

* Fix storing and retrieving of send-to-device messages

* Try to avoid database locks

* Update sync position

* Use latest sync position

* Jiggle about sync a bit

* Fix tests

* Break out the retrieval from the update/delete behaviour

* Comments

* nolint on getResponseWithPDUsForCompleteSync

* Try to line up sync tokens again

* Implement wildcard

* Add all send-to-device tests to whitelist, what could possibly go wrong?

* Only care about wildcard when targeted locally

* Deduplicate transactions

* Handle tokens properly, return immediately if waiting send-to-device messages

* Fix sync

* Update sytest-whitelist

* Fix copyright notice (need to do more of this)

* Comments, copyrights

* Return errors from Do, fix dendritejs

* Review comments

* Comments

* Constructor for TransactionWriter

* defletions

* Update gomatrixserverlib, sytest-blacklist
