On some network conditions, WSARecvFrom() may return WSAECONNRESET or WSAENETRESET error code to indicate that the connection has been broken and should be reset. According to MSDN documentation, WSAECONNRESET mean that the virtual circuit was reset by the remote side executing a hard or abortive close. Also, it would indicate that a previous send operation resulted in an ICMP "Port Unreachable" message. For a datagram socket, WSAENETRESET indicates that the time to live has expired. Previously, hasPendingDatagram() discarded datagrams with these errors and reported no data available. This behavior is incorrect and can lead to infinite "freezing" of the socket. This patch allows to handle these notifications as a result of the readDatagram() call.
