    Flush pending errors in gr_udp_sink on disconnect()
    
    On some systems (e.g., Debian/lenny) UDP errors are reported on the
    following send() or recv() call.  To avoid having errors (such as
    ECONNREFUSED) from an old connection showing up on the first write
    to a new connection, we do a recv() on disconnect() to flush them.
    This may not work for all errors on all systems, but it works in
    some simple cases of interest.

    Rework UDP source and sink, with incompatible API changes
    
    Remove source address specifications for sink; add connect() and
    disconnect() to sink; add get_port() to source; add optional EOF
    signaling (using zero-length packets) to sink and source; modify
    dial_tone, vector, and audio examples to match new code; add qa
    test case.

    Updates to udp source/sink (select(), wait, cleanup)
    
    Use select() to avoid blocking on recv() in gr_udp_source (only known
    way to avoid blocking on Cygwin).
    
    Add wait argument to gr_udp_source to allow waiting for connection
    or accepting lack of connection as EOF; add --no-wait option to
    dial_tone_sink.py.
    
    Remove system dependencies from .h files; remove unused data members
    and (useless?) public open and close functions.

    Discard data in gr_udp_sink until receiver is started.
    
    Also fixes warnings from gcc 4.3 and adds <boost/bind.hpp> for usrp2.

    Use getaddrinfo in gr_udp_{source,sink}
    
    Using getaddrinfo allows more common code between posix and winsock
    systems.  Remove unused variables and #include files.  Close sockets
    when done.

    Changes to gr_udp_{source,sink} for MinGW
    
    Initialize and cleanup after winsock DLL. Interpret winsock error
    codes. Use DWORD instead of timeval for setting timeout.

    Ignore ENOPROTOOPT return from setsockopt(SO_LINGER)
    
    SO_LINGER is not valid for SOCK_DGRAM sockets on Windows, so we
    expect setsockopt to return ENOPROTOOPT (invalid option for
    protocol) on Cygwin and MinGW.  If it happens on any other system
    it should probably be ignored there, too.
