slirp: Add support for stateless DHCPv6
Provide basic support for stateless DHCPv6 (see RFC 3736) so
that guests can also automatically boot via IPv6 with SLIRP
(for IPv6 network booting, see RFC 5970 for details).
Tested with:
qemu-system-ppc64 -nographic -vga none -boot n -net nic \
-net user,ipv6=yes,ipv4=no,tftp=/path/to/tftp,bootfile=ppc64.img
