4f10131848 NI_WITHSCOPEID cleanup. Neither RFC 2553 nor RFC 3493 defines 
NI_WITHSCOPEID, and our getaddrinfo(3) does nothing special
for it, now.

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 
structure in the linked list.  RFC2553 mentions only first.

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)
