- Merged OpenBSD IPv6 patch:

   - [sshd.c sshd.8 sshconnect.c ssh.h ssh.c servconf.h servconf.c scp.1]
     [scp.c packet.h packet.c login.c log.c canohost.c channels.c]
     [hostfile.c sshd_config]
     ipv6 support: mostly gethostbyname->getaddrinfo/getnameinfo, new
     features: sshd allows multiple ListenAddress and Port options. note
     that libwrap is not IPv6-ready. (based on patches from
     fujiwara@rcac.tdi.co.jp)
   - [ssh.c canohost.c]
     more hints (hints.ai_socktype=SOCK_STREAM) for getaddrinfo,
     from itojun@
   - [channels.c]
     listen on _all_ interfaces for X11-Fwd (hints.ai_flags = AI_PASSIVE)
   - [packet.h]
     allow auth-kerberos for IPv4 only
   - [scp.1 sshd.8 servconf.h scp.c]
     document -4, -6, and 'ssh -L 2022/::1/22'
   - [ssh.c]
     'ssh @host' is illegal (null user name), from
     karsten@gedankenpolizei.de
   - [sshconnect.c]
     better error message
   - [sshd.c]
     allow auth-kerberos for IPv4 only
 - Big IPv6 merge:
   - Cleanup overrun in sockaddr copying on RHL 6.1
   - Replacements for getaddrinfo, getnameinfo, etc based on versions
     from patch from KIKUCHI Takahiro <kick@kyoto.wide.ad.jp>
   - Replacement for missing structures on systems that lack IPv6
   - record_login needed to know about AF_INET6 addresses
   - Borrowed more code from OpenBSD: rresvport_af and requisites

+ * 
+ * In the case not using 'configure --enable-ipv6', this getnameinfo.c
