Adds a test for basic WebRTC video codec conformance. 

This tests that the browser conforms to RFC 7742, "WebRTC Video
Processing and Codec Requrements".

It establishes a new subdirectory for protocol-related WebRTC tests.

This directory contains files that test for behavior relevant to webrtc,
but which is specified in protocol specifications from the IETF, not in
API recommendations from the W3C.
The main specifications are given in the following internet-drafts:
- draft-ietf-rtcweb-overview
- draft-ietf-rtcweb-transports
- draft-ietf-rtcweb-security-arch
- draft-ietf-rtcweb-security
- draft-ietf-rtcweb-rtp-usage
- draft-ietf-rtcweb-jsep
- draft-ietf-rtcweb-ip-handling
- draft-ietf-rtcweb-fec
- draft-ietf-rtcweb-data-protocol
- draft-ietf-rtcweb-data-channel
- RFC 7742, "WebRTC Video Processing and Codec Requirements"
- RFC 7874, "WebRTC Audio Codec and Processing Requirements"
An overview of the dependencies involved is in draft-jennings-rtcweb-deps
