e7c0163dfe srandomdev() affords us the opportunity to radically improve, and at the 
same time simplify, the random number selection code.

0a0c02d634 Catch any attempted buffer overflows. The magic numbers in this code 
(512) are a little distressing, but the method really needs to be
extended to allow server-supplied DH parameters anyway.

8e7393fb93 Hack to work around braindeath in libtelnet:sra.c. The sra.o file 
references global variables from telnetd, but is also linked into
telnet as well. I was tempted to back out the last sra.c change
as it is 100% bogus and should be taken out and shot, but for now
this bandaid should get world working again. :-(

eca1a06f99 Clean up telnet's argument processing a bit. autologin and encryption is 
now the default, so ignore the arguments that turn it on. Add a new -y
argument to turn off encryption in case someone wants to do that. Sync
these changes with the man page (including removing the now obsolete
statement about availability only in the US and Canada).

0f2c0f75fe 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.
