This CL adds interfaces for the new video codec factories and wires them up in WebRtcVideoEngine. The default behavior is unmodified however, and the new code is currently unused except for the tests. A follow-up CL will be uploaded for exposing them in the PeerConnectionFactory API: https://codereview.webrtc.org/3004353002/. BUG=webrtc:7925 R=andersc@webrtc.org, stefan@webrtc.org Review-Url: https://codereview.webrtc.org/3007073002 . Cr-Commit-Position: refs/heads/master@{#19828}
