This fixes a problem on old Ubuntu distro causing the Node ID to be the same for multiple hosts.
Additional minor changes:
- removed compilation warnings
- some fixes to code indentation
- mDNS advertisement for all local Sources is implemented by mdns_server.[cpp,hpp] and based on Linux Avahi.
- RTSP server implementation supports DESCRIBE method to return SDP of local Sources and supports persistent connection but doesn't provide service updates via UPDATE method.
- Modified RTSP client to browse for _ravenna_session subtype of _rtsp._tcp services only.
- Modified SAP and mDNS discovery to avoid returning local Sources advertised by the daemon.
- Added "rtsp_port" and "node_id" config parameters.
- rtsp_port is a read/write parameter that contains the port of the RTSP server.
- node_id is a read only parameter that contains the unique daemon identifier used in mDNS and SAP sources announcements.
- Modified session manager to check that every Source and Sink created by the user has a unique name.
- Modified WebUI to visualize node_id and to visualize and edit rtsp_port parameters in Config tab.
- Extended regression test to verify proper behaviour of mDNS/RTSP sources advertisement and discovery.
- Modified REST API to browse remote sources to allow browsing of SAP, mDNS and all sources via HTTP GET /api/browse/sources/[all|mdns|sap].
- Amended daemon documentation.
Added to the WebUI the possibility to directly select a remote source SDP file for a Sink.
