Steffen Klassert 2f32b51b60 xfrm: Introduce xfrm_input_afinfo to access the the callbacks properly 
IPv6 can be build as a module, so we need mechanism to access
the address family dependent callback functions properly.
Therefore we introduce xfrm_input_afinfo, similar to that
what we have for the address family dependent part of
policies and states.

Steffen Klassert 70be6c91c8 xfrm: Add xfrm_tunnel_skb_cb to the skb common buffer 
IPsec vti_rcv needs to remind the tunnel pointer to
check it later at the vti_rcv_cb callback. So add
this pointer to the IPsec common buffer, initialize
it and check it to avoid transport state matching of
a tunneled packet.
