#2 Client side: closing TCP Socket on server is handled

[imba]

1. When MrcpMessageDecoder reads from TcpSocket and TcpSocket is closed on remote side, it starts infinite loop with 100% CPU load. This is fixed - an exception is thrown in this case.
2. A method which notifies about socket closing is added to MrcpEventListener.
