Maciej Żenczykowski 5f68982d02 clat: add support for ESP, mirroring existing GRE support
This relies on some pretty heavy duty magic on the side of the PLAT
nat gateway in order to be useful.

It might not even work... but it already doesn't work, so it can't
be worse then the current state where we simply discard these packets.

known problems/assumptions:
- does not handle protocols other than ICMP, UDP, TCP and GRE/ESP
- assumes the handset has its own (routed) /64 ipv6 subnet
- assumes the /128 ipv6 subnet it generates can use the nat64 gateway
- assumes the nat64 gateway has the ipv4 address in the last 32 bits of the ipv6 address (that it uses a /96 plat subnet)
