ejurgensen f63d103753 [raop] Add support for Apple TV device verification, required by tvOS 10.2 (fix for issue #377)
- also change how speakers are saved/retrieved from the db
- add generic authorization methods in outputs.c and player.c
- let filescanner read *.verification files (containing PIN)
- configure options to enable and disable, since libsodium is required
