Subject: Implement a Logging Sink for WebRTC

WebRTC logs now pass out of the webrtc library into a logging sink,
which converts them into SecondLife.log compatable logging calls.

This includes fatal errors and asserts, which are now logged into
SecondLife.log, and should be available in the crash logger.
