Support synchronous SDP state validation

Validate answer signaling states when their operations-chain entries
begin. Allow browser callers to opt into WebRTC-PC's createOffer state
restriction while native JSEP callers can generate offers in every
non-closed state.

Report failures directly through the observer so an immediately run
operation can reach Blink synchronously without changing the ordering of
queued operations. Handle closed peer connections consistently for both
operations.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See here for instructions on how to get started developing with the native code.
