More sane next batch handling, typing notification tweaks, give invites their own stream position, device list fix (#1641)

Browse source 
* Update sync responses

* Fix positions, add ApplyUpdates

* Fix MarshalText as non-pointer, PrevBatch is optional

* Increment by number of read receipts

* Merge branch 'master' into neilalexander/devicelist

* Tweak typing

* Include keyserver position tweak

* Fix typing next position in all cases

* Tweaks

* Fix typo

* Tweaks, restore StreamingToken.MarshalText which somehow went missing?

* Rely on positions from notifier rather than manually advancing them

* Revert "Rely on positions from notifier rather than manually advancing them"

This reverts commit 53112a62cc3bfd9989acab518e69eeb27938117a.

* Give invites their own position, fix other things

* Fix test

* Fix invites maybe

* Un-whitelist tests that look to be genuinely wrong

* Use real receipt positions

* Ensure send-to-device uses real positions too
