Fix multicast join/leave when binding to QHostAddress::Any.
On OS X and Windows, this was not working, because the socket was being bound in v6 mode (due to ::Any being for dual mode), but the address passed was a v4 address, meaning it took the wrong codepath. Linux, strangely, apparently works anyway. This is fixable in OS X (by using the v6 join path when bound in v6/dual mode), but the same fix doesn't work on Windows, failing with WSAEADDRNOTAVAIL. Don't allow this behaviour, and provide a sane error message telling the user what to do instead.
