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.

Send a TCP RST in response to a TCP SYN-ACK on a listening endpoint
...
This change better follows what is outlined in RFC 793 section 3.4 figure 12
where a listening socket should not accept a SYN-ACK segment in response to a
(potentially) old SYN segment.
Tests: Test that checks the TCP RST segment sent in response to a TCP SYN-ACK
segment received on a listening TCP endpoint.

This change does not make use of SACK information but adds support to track
SACK information and store it in the endpoint.
The actual SACK based recovery will be in a separate CL.
