To simplify lifetime management of "listening" UDP sockets, UDP flow
support needs to duplicate existing bound sockets. Those duplicates will
be close()d when their corresponding flow expires, but we expect the
original to still receive datagrams as always. That is, we expect the
close() on the duplicate to remove the duplicated fd, but not to close the
underlying UDP socket.
Add a test program to doc/platform-requirements to verify this requirement.
