Merge remote-tracking branch 'syncthing/pr/1995'

* syncthing/pr/1995:
  Add switch to disable relays
  Do not start relay service unless explicitly asked for, or global announcement server is running
  Add dynamic relay lookup (DDoS relays.syncthing.net!)
  Discovery clients now take an announcer, global discovery is delayed
  Expose connection type and relay status in the UI
  Add dependencies (fixes #1364)
  Check relays for available devices
  Add incoming connection relay service
  Add unsubscribe to config
  Connections have types
  Large refactoring/feature commit
