Clamp TCP receive window to MSS multiplied by maximum burst size.
...
This is a conservative bound; if we don't have enough buffers
to receive more than four segments, clearly we shouldn't advertise
our ability to.
It however will only work reliably with exactly one TCP connection
continuously receiving; for two, another window adjustment mechanism
will be needed for reliable reception.

Improve handling of TCP ACK packets in FIN-* states.
...
Previously, sockets could get stuck in the CLOSING state, after
the sequence described in the new test_mutual_close_with_data_2.
The root cause was that some state machine transitions got
folded into ACK handling.
Now, all transitions are handled in the same match statement,
and ACK handling is broken up around it.
