IPv6 specific thing is wrongly removed from transformation at net-2.6.25.
This patch recovers it with current design.
o Update "path" of xfrm_dst since IPv6 transformation should
care about routing changes. It is required by MIPv6 and
off-link destined IPsec.
o Rename nfheader_len which is for non-fragment transformation used by
MIPv6 to rt6i_nfheader_len as IPv6 name space.

It appears that I've managed to create two different functions both
called xfrm6_tunnel_output. This is because we have the plain tunnel
encapsulation named xfrmX_tunnel as well as the tunnel-mode encapsulation
which lives in the files xfrmX_mode_tunnel.c.
This patch renames functions from the latter to use the xfrmX_mode_tunnel
prefix to avoid name-space conflicts.

The NETFILTER_ADVANCED option hides lots of the rather obscure netfilter
options when disabled and provides defaults (M) that should allow to
run a distribution firewall without further thinking.
Defaults to 'y' to avoid breaking current configurations.

Now that external users may increment the counters directly, we need
to ensure that udp_stats_in6 is always available. Otherwise we'd
either have to requrie the external users to be built as modules or
ipv6 to be built-in.
This isn't too bad because udp_stats_in6 is just a pair of pointers
plus an EXPORT, e.g., just 40 (16 + 24) bytes on x86-64.

This is similar to the change already done for IPIP tunnels.
Once created, a SIT tunnel can't be bound to another device.
To reproduce:
# create a tunnel:
ip tunnel add tunneltest0 mode sit remote 10.0.0.1 dev eth0
# try to change the bounding device from eth0 to eth1:
ip tunnel change tunneltest0 dev eth1
# show the result:
ip tunnel show tunneltest0
tunneltest0: ipv6/ip remote 10.0.0.1 local any dev eth0 ttl inherit
Notice the bound device has not changed from eth0 to eth1.
This patch fixes it. When changing the binding, it also recalculates the
MTU according to the new bound device's MTU.
