	CONFIG_NET_NEW_BIND_SEMANTICS:
	- as a result of local discussion, we've decided not to introduce

	(found by bindtest(1) tool)

2001/05/22	yoshfuji
	* {usagi,src}/bindtest: build and install bindtest. (from KAME)

2001/05/22	yoshfuji

	- icmpv6 checksum error is now considered as KERN_WARNING level.
	- print type, code and source address against unknown icmpv6 message
	if CONFIG_IPV6_DEBUG is set; otherwise, don't print anything.
	- Silent discard invalid Node Information Query message without
	CONFIG_IPV6_NODEINFO_DEBUG.
	* kernel/linux2{2,4}/net/ipv6/mcast.c:
	- socket creation failure is now on KERN_ERR level.

	net/ipv6/addrconf.c,net/ipv6/af_inet6.c,Documentation/Configure.help},
	src/iproute2/ip/iptunnel.c, src/net-tools/iptunnel.c:
	tunlXX device can transport ipv6 packet with CONFIG_NET_IPIP_IPV6;
	IPv6 over IPv4 support and IPv4 over IPv4 support has been integrated
	and sitXX will be dissappeared.

	Note: You should use patched command(s) to manipulate tunnels.

	XXX: modulized ipv6 and ip tunneling interactions.

	* kernel/linux2{2,4}/net/{ipv4/udp.c,ipv4/tcp_ipv4.c,
	ipv6/udp.c,ipv6/tcp_ipv6.c} etc.: New bind(2) semantics has been 
	introduced with CONFIG_NET_NEW_BIND_SEMANTICS.  Hilights are:
	- Now we do not allow double bind as default;  it is allowed only if 
	IPV6_V6ONLY socket option is set to the inet6 socket.
	- implemented SO_REUSExxx more strictly.
	- binding more specific interfaces attack are forbidden.
	XXX: fast-reuse
	XXX: more description
