Changes

| Tasks would include finishing the sndio backend for OpenBSD (Bug #911450), upstreaming to webrtc.org the patches already commited to mozilla (#807492 and its dependencies), and make sure the webrtc integration tests also run fine on major BSDs. The project will be successful if an A/V call can be done from firefox nightly from a BSD to another firefox instance on Linux or Windows, and also in-between different BSDs, using the tests from http://mozilla.github.io/webrtc-landing/ and https://apprtc.appspot.com/. Proper testing with Talkilla would definitely be a win too.
