We add almost full TCP state machine in filter-rewriter, except
TCPS_LISTEN and some simplify in VM active close FIN states.
The reason for this simplify job is because guest kernel will track
the TCP status and wait 2MSL time too, if client resend the FIN packet,
guest will resend the last ACK, so we needn't wait 2MSL time in filter-rewriter.
After a net connection is closed, we didn't clear its related resources
in connection_track_table, which will lead to memory leak.
Let's track the state of net connection, if it is closed, its related
resources will be cleared up.
