 * Ecmt server observer interface.

 * A client application that wishes to receive Ecmt server notification

 * messages such as connection / disconnection indications must implement

 * this interface and then register itself to Ecmt server using

 * REcmt::SetServerObserverL. There is at least one such client in the

 * system - the EcmtGui application. Other clients shoudn't be

 * concerned with the state of Ecmt server.
