Makes the RTCSessionDescription argument optional for setLocalDescription(). Previously, it required a value returned by createOffer() or createAnswer(). With this change Chromium generates the the offer or answer implicitly when no argument is provided. This avoids possible edge-case races.
Motivation
This is part of "Perfect Negotiation", which makes signaling in WebRTC race-free and less error-prone. For more details, see https://docs.google.com/presentation/d/1xcvf0udNeSH7s1FOY7RRqr1dEFvokZjn-MZPjwy3iXQ/edit?usp=sharing.
