cee8823e5c Added handling of session ID <sess-id> and session version <sess-version> in the Origin ("o=") field of the Sources SDP files.
Session ID is the Node ID plus the source ID.
Session version is the session ID plus an increasing version identifier.
This fixes issue #10 and allows Dante Controller to properly handle the daemon Sources.

371090e7b9 Changes to SessionManager class to handle notifications for source updates triggered when the PTP GMID clock changes or the driver sample rate changes.
SessionManager allows the registration of source update observers and delivers via callbacks the above notifications.
RTSP server modified to register to source update notifications and to send updates to clients via ANNOUNCE method.

d41b67d006 Set of changes to add support for mDNS sources SDP update via RTSP ANNOUNCE method as described by Ravenna.
- 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

0dbfe78a10 - Added support for mDNS/RTSP sources advertisement compatible with Ravenna standard.
- 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.

5deb6c1927 Added to the daemon the support for Multicast DNS (using Linux Avahi) to allow discovery of remote audio sources and of RTSP for SDP transfer.
Added to the WebUI the possibility to directly select a remote source SDP file for a Sink.

New files:
daemon/mdns_client.hpp,cpp -> mDNS client implementation using Avahi client library
daemon/rtsp_client.hpp,cpp -> RTSP client implementation used to transfer SDP file
daemon/utils.cpp -> used for common utility functions
.clang-format -> added clang-format configuration file

Modified files:
daemon/CMakeList.txt -> added support for Avahi and option WITH_AVAHI=[yes/no] to compile the daemon with or without Avahi mDNS support
daemon/config.hpp,cpp -> added configuration option mdns_enabled to enable or disable mDNS discovery at runtime
daemon/json.cpp -> extended JSON config with mdns_enabled option
daemon/browser.hpp,cpp -> added support for mDNS client to the browser
daemon/session_manager.cpp -> added support for RTSP protocol to Source URL field and fixed issue with SDP file parsing
webui/RemoteSources.js -> added visualization of mDNS remote sources
webui/SinkEdit.js -> added the possibility to directly select a remote source SDP file for a Sink
webui/SourceInfo.js -> added visualization of protocol source (SAP, mDNS or local) for a source
ubuntu-packages.sh -> added libavahi-client-dev to the list of required packages
build.sh -> added WITH_AVAHI=yes option when invoking CMake
README.md -> added notes about mDNS support via Avahi
daemon/README.md -> added notes about mDNS support via Avahi, support for RTSP protocol in source and new mdns_enabled config param

Additional minor changes to remaining files.
