/**
* WvIPRawStream can send and receive packets on a connectionless IP socket.
*
* In the constructor, the socket is attached using bind() to the given
* _local address. If the address is 0.0.0.0, all addresses on the local
* host are used; if the port is 0, an available port number is chosen
* automatically.
*
* If the _rem address is 0.0.0.0, the port is not connect()ed. That means
* it can receive packets from anywhere and send them to anywhere. The
* src() and setdest() functions are useful for this. If _rem is not 0.0.0.0,
* connect() is called and the socket will only accept data to/from the
* specified remote UDP address.
*
* Buffering: all the usual WvStream-style input buffering is available,
* including getline(), but because input packets may get lost it is of
* limited usefulness. Buffering will cause particular confusion if the
* socket is not connect()ed.
