Use PacketBuffers, rather than VectorisedViews, in netstack.
...
PacketBuffers are analogous to Linux's sk_buff. They hold all information about
a packet, headers, and payload. This is important for:
* iptables to access various headers of packets
* Preventing the clutter of passing different net and link headers along with
VectorisedViews to packet handling functions.
This change only affects the incoming packet path, and a future change will
change the outgoing path.
