d5cf830ef1 Determine the host name using an array size of 
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.

9e9a43bdec Ensure that things returned by gethostname() and 
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)

51d8a6713f After receiving a connection and doing a reverse 
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.

3cc1b1bf9c Old stuff laying around: Don't use a function called getstr(), that has 
nasty consequences when the system curses is ncurses as this conflicts
with a ncurses funciton and causes recursion.

f05011e686 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 will be incorporated in the crypto version of telnetd.

This resolves bin/771 and bin/1037.

ecf74fe675 The final negotiation of DO_BINARY in the LINEMODE portion of the telnetd code 
causes some clients that do not support linemode to mis-interpret the return
key (i.e. double returns).
The fix is to only do the state check for binary options if linemode will
be used.
Closes PR#505.
