the behavior was introduced in 1.8 -> 1.9, by itojun, and it was
not a correct behavior.
even if we may be able to connect to the the returned addresses,
filtering them out is not a correct thing to do. for example, even if
you have partial unreachablility in IPv4, gethostbyname(3) will return
IPv4 addresses in the unreachable network nonetheless.
input filter to ensure we don't end up with a cached copy of the page
in the wrong byte-order for the host cpu.
This fixes a fatal bug which bites when the DB 'lorder' is different
to the cpu's, and a cached page is accessed soon after it was flushed
to disk.
AF_INET6 wildcard listening socket. heavily documented in ip6(4).
net.inet6.ip6.bindv6only defines default value. default is 1.
"options INET6_BINDV6ONLY" removes any code fragment that supports
IPV6_BINDV6ONLY == 0 case (not defopt'ed as use of this is rare).
this allows you to disable/enable ICMPv6 node information query/reply
processing (which tells remote end the gethostname(3) setting, interface
addresses on the node, and some other things - documented in
draft-ietf-ipngwg-icmp-name-lookup* or something alike).
to test it, try ping6 -w ::1 with nodeinfo=0 and nodeinfo=1.
(sync with kame change)
getaddrinfo(3): result from gethostby* will be broken if we call it again.
deep-copy them. we have sa_len so configure them.
getnameinfo(3): we have sa_len so configure them.
getnameinfo(3) globs ai_socktype and ai_protocol correctly.
KAME scopeid extension is implemented.

bump up shlib minor
(may not be necessary, but rather big difference in behavior - especially
ai_flags)
On platforms where we can use weak aliases, use
__weak_alias(__errno, __errno_func);
and on platforms where we cannot, just compile the function as
__errno, since on those platforms we cannot make libc thread-safe,
at least using this trick.
Are there any platforms where we cannot do __weak_alias() anymore?
(as originally declared in System V) to "char * const []", as was done in
1003.2 and subsequently propagated into XPG4.
