"ssl-" configuration settings

[Jan-Piet Mens]

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. :-)
