MAXHOSTNAMELEN and call trimdomain() before implementing
the -u option.
This allows local hosts of a lan with a long domain name to
appear properly in utmp by base host name (w/o domain) rather
than by IP number.
friends are terminated and allow for a maximum
host name length of MAXHOSTNAMELEN - 1.
Put parenthesis around sizeof args.
Make some variables static.
Fix telnetd -u (broken by my last commit)
Prompted by: bde
lookup on the incoming IP, do a forward lookup on
the result and make sure that the IP is in the
resulting list. If it's not, put the IP number
in utmp/wtmp instead of the rogue name.

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 will be incorporated in the crypto version of telnetd.
This resolves bin/771 and bin/1037.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
were chopped off of the function call and garbage was passed instead.
The solution involves making some variable globals as well as fixing the
call to have all the arguments.
