f743d11975 Fix a buffer overflow from a long local hostname.
Obtained from:	OpenBSD

fbbed1ea76 Fix buffer overflow when DISPLAY is longer than 43 characters. This
is not exploitable because telnet doesn't run with elevated privs.

Didn't fix all the other potential buffer overflows.  Would be a good
task for someone who has lots of time to carefully study each case
because cut and paste solutions are dangerous for this code base.

Added $FreeBSD$ in the same way that command.c did it.

93709ddb08 simplify and correct name resolution in tn().
XXX what is the goal of af_switch()?  it seems to me it is not necessary
any more with getaddrinfo(3) fix for correct name-resolution ordering.

1d1ade86f0 Fix bugs in telnet.
Sorry there were still several bugs.
   -error retry at af missmatch was incomplete.
   -af matching for source addr option was wrong
   -socket was not freed at retry.

960e15a70b Add more dual stack consideration.
-Should retry as much as possible when some of source
     routing intermediate hosts' address families missmatch
     happened.
     (such as when a host has only A record, and another host
     has each of A and AAAA record.)

    -Should retry as much as possible when dest addr and
     source addr(specified with -s option) address family
     missmatch happend

0bd288cd6c 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.

Discovered at checking recent KAME repository change, noticed by itojun.

0886891cb5 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

Telnet has nothing to do with this, it's telnetd and telnetd
doesn't use KLUDGELINEMODE so that theory is washed up.  Anyway,
