Import Lite2's src/usr.bin/telnet. The README is still on the vendor

branch and importing it gives some anachronisms.  tn3270.c is still on
the vendor branch and importing it just changes a memcpy to memmove.

+
+May 30, 1995
+
+This release represents what is on the 4.4BSD-Lite2 release, which
+should be the final BSD release.  I will continue to support of
+telnet, The code (without encryption) is available via anonymous ftp
+from ftp.cray.com, in src/telnet/telnet.YY.MM.DD.NE.tar.Z, where
+YY.MM.DD is replaced with the year, month and day of the release.
+If you can't find it at one of these places, at some point in the
+near future information about the latest releases should be available
+from ftp.borman.com.
+
+In addition, the version with the encryption code is available via
+ftp from net-dist.mit.edu, in the directory /pub/telnet.  There
+is a README file there that gives further information on how
+to get the distribution.
+
+Questions, comments, bug reports and bug fixes can be sent to
+one of these addresses:
+		dab@borman.com
+		dab@cray.com
+		dab@bsdi.com
+
+This release is mainly bug fixes and code cleanup.
+
+	Replace all calls to bcopy()/bzero() with calls to
+	memmove()/memset() and all calls to index()/rindex()
+	with calls to strchr()/strrchr().
+
+	Add some missing diagnostics for option tracing
+	to telnetd.
+
+	Add support for BSDI 2.0 and Solaris 2.4.
+
+	Add support for UNICOS 8.0
+
+	Get rid of expanded tabs and trailing white spaces.
+
+	From Paul Vixie:
+		Fix for telnet going into an endless spin
+		when the session dies abnormally.
+
+	From Jef Poskanzer:
+		Changes to allow telnet to compile
+		under SunOS 3.5.
+
+	From Philip Guenther:
+		makeutx() doesn't expand utmpx,
+		use pututxline() instead.
+
+	From Chris Torek:
+		Add a sleep(1) before execing login
+		to avoid race condition that can eat
+		up the login prompt.
+		Use terminal speed directly if it is
+		not an encoded value.
+
+	From Steve Parker:
+		Fix to realloc() call.  Fix for execing
+		login on solaris with no user name.
+
+January 19, 1994
+
+This is a list of some of the changes since the last tar release
+of telnet/telnetd.  There are probably other changes that aren't
+listed here, but this should hit a lot of the main ones.
+
+   General:
+	Changed #define for AUTHENTICATE to AUTHENTICATION
+	Changed #define for ENCRYPT to ENCRYPTION
+	Changed #define for DES_ENCRYPT to DES_ENCRYPTION
+
+	Added support for SPX authentication: -DSPX
+
+	Added support for Kerberos Version 5 authentication: -DKRB5
+
+	Added support for ANSI C function prototypes
+
+	Added support for the NEW-ENVIRON option (RFC-1572)
+	including support for USERVAR.
+
+	Made support for the old Environment Option (RFC-1408)
+	conditional on -DOLD_ENVIRON
+
+	Added #define ENV_HACK - support for RFC 1571
+
+	The encryption code is removed from the public distributions.
+	Domestic 4.4 BSD distributions contain the encryption code.
+
+	ENV_HACK: Code to deal with systems that only implement
+		the old ENVIRON option, and have reversed definitions
+		of ENV_VAR and ENV_VAL.  Also fixes ENV processing in
+		client to handle things besides just the default set...
+
+	NO_BSD_SETJMP: UNICOS configuration for
+		UNICOS 6.1/6.0/5.1/5.0 systems.
+
+	STREAMSPTY: Use /dev/ptmx to get a clean pty.  This
+		is for SVr4 derivatives (Like Solaris)
+
+	UTMPX: For systems that have /etc/utmpx. This is for
+		SVr4 derivatives (Like Solaris)
+
+	Definitions for BSDI 1.0
+
+	Definitions for 4.3 Reno and 4.4 BSD.
+
+	Definitions for UNICOS 8.0 and UNICOS 7.C
+
+	Definitions for Solaris 2.0
+
+	Definitions for HP-UX 8.0
+
+	Latest Copyright notices from Berkeley.
+
+	FLOW-CONTROL: support for RFC-XXXx
+
+
+   Client Specific:
+
+	Fix the "send" command to not send garbage...
+
+	Fix status message for "skiprc"
+
+	Make sure to send NAWS after telnet has been suspended
+	or an external command has been run, if the window size
+	has changed.
+
+	sysV88 support.
+
+   Server Specific:
+
+	Support flowcontrol option in non-linemode servers.
+
+	-k Server supports Kludge Linemode, but will default to
+	   either single character mode or real Linemode support.
+	   The user will have to explicitly ask to switch into
+	   kludge linemode. ("stty extproc", or escape back to
+	   to telnet and say "mode line".)
+
+	-u Specify the length of the hostname field in the utmp
+	   file.  Hostname longer than this length will be put
+	   into the utmp file in dotted decimal notation, rather
+	   than putting in a truncated hostname.
+	
+	-U Registered hosts only.  If a reverse hostname lookup
+	   fails, the connection will be refused.
+
+	-f/-F
+	   Allows forwarding of credentials for KRB5.
