Flags defined in the testing package may conflict
with real flags defined in the main package, or in
any other imported package.

This change makes them less likely to be used for
other purposes.

I'm not sure if it's 100% correct wrt the HTML5 specification,
but the test suite has plenty of HTML comment test cases, and
we'll shake out any tokenization bugs as the parser improves its
coverage.

notes:
Darwin is very particular about joining a multicast group if the
listneing socket is not created in "udp4" mode, the other supported
OS's are more flexible.

A simple example sets up a socket to listen on the mdns/bonjour
group 224.0.0.251:5353

// ensure the sock is udp4, and the IP is a 4 byte IPv4
socket, err := net.ListenUDP("udp4", &net.UDPAddr {
        IP: net.IPv4zero,
        // currently darwin will not allow you to bind to
        // a port if it is already bound to another process
        Port: 5353,
})
if err != nil {
        log.Exitf("listen %s", err)
}
defer socket.Close()
err = socket.JoinGroup(net.IPv4(224, 0, 0, 251))
if err != nil {
        log.Exitf("join group %s", err)
}
