Test for bug 2211.
https://www.nsnam.org/bugzilla/show_bug.cgi?id=2211
NOTE: It is a valgrind testcase, it contains no ASSERTs.
Test creates one node and sets up two TCP sockets on the loopback with default parameters: CWND = 1, MTU = 536. Sender socket sends 3 segments. When first segment is acknowledged, cwnd is raised to 2. Then, two segments are sent and arrive into receive buffer. Until bugfix, the following happened: Ipv4EndPoint::ForwardUp was called for both second and third segment. These calls scheduled two Ipv4EndPoint::DoForwardUp events. To demonstrate the bug, test case closes the receiver socket after receiving the second segment. As a result, Ipv4EndPoint is destroyed. However, Ipv4EndPoint::DoForwardUp is already scheduled for third segment. It is a use-after-free bug.
