Refactor BaseChannel creation in PeerConnection

This changes the CreateVoiceChannel/CreateVideoChannel helper
methods in PeerConnection to return the created channel instead of
setting it directly. That allows the Unified Plan version of
SetLocalDescription to use the same factory methods without the
assumption that there is at most one voice and one video channel.

Also simplifies and deduplicates the logic for determining the
transport name for a given channel in the presence of BUNDLE.

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 http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
