Support sqlite in addition to postgres (#869)

Browse source 
* Move current work into single branch

* Initial massaging of clientapi etc (not working yet)

* Interfaces for accounts/devices databases

* Duplicate postgres package for sqlite3 (no changes made to it yet)

* Some keydb, accountdb, devicedb, common partition fixes, some more syncapi tweaking

* Fix accounts DB, device DB

* Update naffka dependency for SQLite

* Naffka SQLite

* Update naffka to latest master

* SQLite support for federationsender

* Mostly not-bad support for SQLite in syncapi (although there are problems where lots of events get classed incorrectly as backward extremities, probably because of IN/ANY clauses that are badly supported)

* Update Dockerfile -> Go 1.13.7, add build-base (as gcc and friends are needed for SQLite)

* Implement GET endpoints for account_data in clientapi

* Nuke filtering for now...

* Revert "Implement GET endpoints for account_data in clientapi"

This reverts commit 4d80dff4583d278620d9b3ed437e9fcd8d4674ee.

* Implement GET endpoints for account_data in clientapi (#861)

* Implement GET endpoints for account_data in clientapi

* Fix accountDB parameter

* Remove fmt.Println

* Fix insertAccountData SQLite query

* Fix accountDB storage interfaces

* Add empty push rules into account data on account creation (#862)

* Put SaveAccountData into the right function this time

* Not sure if roomserver is better or worse now

* sqlite work

* Allow empty last sent ID for the first event

* sqlite: room creation works

* Support sending messages

* Nuke fmt.println

* Move QueryVariadic etc into common, other device fixes

* Fix some linter issues

* Fix bugs

* Fix some linting errors

* Fix errcheck lint errors

* Make naffka use postgres as fallback, fix couple of compile errors

* What on earth happened to the /rooms/{roomID}/send/{eventType} routing
