6484396e99 Sshd writes connected host into utmp directly. If the connection is
via IPv6, the hostname is trimed due to the length of IPv6 address.
This change saves it as possible.
I have a grudge against the shortage of UT_HOSTSIZE.

4efe647d8b We should see the ai_canonname menber of the first addrinfo

88f853e037 Since crypto/openssh/login.c was changed to use realhostname_sa(),
when connecting via IPv6, hostname was not recorded to utmp anymore.
Because, if hostname is longer than buffer size, getnameinfo() returns
with ENI_MEMORY.

01d81a0351 Avoid core dump when ai_canonname is NULL.
(Now this happens for numeric addrs, as getaddrinfo() 1.3 -> 1.4 change)
