c7be24c970 If the uid of the attempted authentication is 0 and if the pty is 
insecure, do not succeed. Copied from login.c. This functionality really
should be a PAM module.

036790848a 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).

6a1fe28e41 Reactivate SRA. 
Make handling of SIGINT and SIGQUIT follow SIGTSTP in TerminalNewMode().
This allows people to break out of SRA authentication if they wish to.

I just mistakenly commited this to RELENG_4. I have contacted Jordan to see
about how to fix this. Pass the pointy hat.

1d1ade86f0 Fix bugs in telnet. 
Sorry there were still several bugs.
   -error retry at af missmatch was incomplete.

960e15a70b Add more dual stack consideration. 
-Should retry as much as possible when some of source
     routing intermediate hosts' address families missmatch
     happened.
     (such as when a host has only A record, and another host
     has each of A and AAAA record.)

    -Should retry as much as possible when dest addr and
     source addr(specified with -s option) address family
     missmatch happend

0bd288cd6c Add NI_NAMEREQD flag to getnameinfo() call. Without this flag, 
getnameinfo() don't return error at name resolving failure.
But it is used at doaddrlookup(-N) case in telnet, error need to be
returned to correctly initialize hostname buffer.

Discovered at checking recent KAME repository change, noticed by itojun.

0f8c8396c5 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.
