It's the year 2016, and I think it's time to stop using the word SSL 
As such: would it be possible to either rename or introduce aliases or
synonyms for the Unbound configuration settings which are called "ssl-*" ?
ssl-upstream -> tls-upstream
ssl-service-key -> tls-service-key
ssl-service-pem -> tls-service-pem
ssl-port -> tls-port
Of course the documentation would need a s/SSL/TLS/g as well, but I
would gladly contribute a patch for that if desired.
