SMACK-419 PacketWriter: Only flush if queue is empty

SMACK-417 If both PacketReader and PacketWriter fail at the same time, connectionClosedonError() is called two times

Refactored notifyConnectionError() and notifyReconnection() from PacketReader to XMPPConnection. Made PacketReader.done and PacketWriter.done volatile. Prevent duplicate connectionClosedonError() calls by making the method synchronzied and protected them with an enter guard: if (packetReader.done && packetWriter.done) return;

SMACK-225 Modified DNSUtils to return a default HostAddress when no DNS resolver is available.  This restores the previous default behaviour.
