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

Browse source 
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;
