845ce56d7b 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.

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.

d16b9a5166 PR: bin/771 and bin/1037 are resolved by this change 
This change changes the default handling of linemode so that older and/or
stupider telnet clients can still get wakeup characters like <ESC> and
<CTRL>D to work correctly multiple times on the same line, as in csh
"set filec" operations.   It also causes CR and LF characters to be read by
apps in certain terminal modes consistently, as opposed to returning
CR sometimes and LF sometimes, which broke existing apps.  The change
was shown to fix the problem demonstrated in the FreeBSD telnet client,
along with the telnet client in Solaris, SCO, Windows '95 & NT, DEC OSF,
NCSA, and others.

A similar change was incorporated in the non-crypto version of telnetd.

This resolves bin/771 and bin/1037.
