 1.12  06-Feb-2005  perry de-__P, ANSIfy function declarations, remove obsolete "register" declarations.
 1.11  07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22284, verified by myself.
 1.10  14-Jul-2003  itojun remove unneeded #ifdefs. improves readability.
(confirmed that exact same *.o is produced)
 1.9  20-Aug-2001  wiz Add some (const char *) casts per bin/13667 by Brian Ginsbach.
 1.8  19-Jul-2001  itojun bound-check all "*nfrontp++" code. from openbsd/heimdal.
bark if file descriptor goes above FD_SETSIZE. from openbsd.

XXX needs more checking.
XXX what is tab stop size for this code? need more consistency...
XXX we should really remove #ifdef CRAY, UNICOS5 and such.
we just cannot read it through.
 1.7  22-Jun-2000  thorpej Bring the telnet situation back into better shape. Specifically,
pull in just about all of the differences from the crypto-us telnet
suite (which includes Kerberos 4 and connection encryption support).
Also bring in the Kerberos 5 support from the Heimdal telnet, and
frob a little so that it can work with the non-Heimdal telnet suite.

There is still some work left to do, specifically:
- Add Heimdal's ticket forwarding support to the Berkeley Kerberos 4
module.
- Add connection encryption support to the Heimdal Kerberos 5
module. Hints on this can be taken from the MIT Kerberos 5
module which still exists in crypto-us.

However, even with the shortcomings listed above, this is a
better situation than using the stock Heimdal telnet suite,
which does not understand the IPSec policy stuff, and is also
based on much older code which contains bugs that we have already
fixed in the NetBSD sources.
 1.6  01-Feb-2000  assar branches: 1.6.4;
(net_write): rename to telnet_net_write
 1.5  16-Oct-1997  mikel kill old-style getenv() declaration
 1.4  08-Oct-1997  mrg WARNS?=1. RCS ids.
 1.3  28-Feb-1996  thorpej RCS id cosmetics.
 1.2  24-Feb-1996  jtk update to telnetd from 95.10.23 version. Includes Borman's scrub_env()
to keep stuff out of the environment on the way to exec (we already have
one in the state machine that keeps them from arriving over the wire, so
this should be redundant, but it'll make any further updates easier to
have it present).

also, RCS Id police.
 1.1  25-Feb-1994  cgd branches: 1.1.1;
new telnetd from ftp.cray.com. Encryption support ripped out, pending
figuring out what to do about it...
 1.1.1.1  24-Sep-1994  mycroft Import original 4.4-Lite version.
 1.6.4.2  29-Jul-2001  jhawk Pull up revision 1.8 (requested by itojun):
Security-related fixups for telnet
Bound-check all "*nfrontp++" code. From OpenBSD and Heimdal.
Complain if file descriptor goes above FD_SETSIZE. From OpenBSD.
 1.6.4.1  22-Jun-2000  thorpej Update from trunk:
