HPN, nonecipher in 8.4

[javocado]

I have some questions about HPN and ssh, specifically:

- does 8.4-RELEASE have HPN ssh built in by default?

- if the only reason I ever installed openssh-portable port was to get HPN,
is there any reason to add that port anymore on 8.4?

- if I would like to still use nonecipher, what is the easiest way to get
it, given a stock, standard 8.4-RELEASE install?

Thanks
