Changes:
This version uses the latest release of the eXosip library, which leads to many new SIP features: reINVITE, INVITE without SDP, and handling of video-fast-update requests in SIP INFO messages and early media. It also integrates the experimental and promising SNOW video codec of the ffmpeg project.
