Add SRA authentication to src/crypto/telnet.
SRA does a Diffie-Hellmen exchange and then DES-encrypts the authentication data. If the authentication is successful, it also sets up a session key for DES encryption. SRA was originally developed at Texas A&M University. This code is probably export restricted (despite the fact that I originally found it at a University in Germany). SRA is not perfect. It is vulnerable to monkey-in-the-middle attacks and does not use tremendously large DH constants (and thus an individual exchange probably could be factored in a few days on modern CPU horsepower). It does not, however, require any changes in user or administrative behavior and foils session hijacking and sniffing. The goal of this commit is that telnet and telnetd end up in the DES distribution and that therefore an encrypted session telnet becomes standard issue for FreeBSD.
