- modified SessionManager class to register and trigger observer callbacks when a new session is added or removed - moved MDNSServer out of the SessionManager and added instantiation in the daemon main - MDNSServer instance registers to SessionManager to receive source add & remove events and invokes appropiate Avahi client operation - RTSPServer instance registers to SessionManager to receive source update events. In case of update It sends RTSP ANNOUNCE (with the new SDP) to the connected RTSP clients that previously requested (via DESCRIBE method) the SDP file for the specific source - removed disconnetion timeout handling in RTSPServer. RTSPServer connections are now persistent
