http://www.freedb.org/ is shutting down at the end of March 2020 so this basically rips off all the freedb code and just makes libkcddb a musicbrainz frontend. Ideally we'd kill libkcddb but there's a few apps still using it, so let's do this maintaince bump. Can anyone spend some minutes reviewing? Cheers, Albert
