Create a peer connection factory builder

Similar to the builder on android: https://cs.chromium.org/chromium/src/third_party/webrtc/sdk/android/api/org/webrtc/PeerConnectionFactory.java?rcl=b90e63c620877712e45ee320cfa25cb825bf5373&l=134

1. A builder will allow us to choose what module factories to provide and use default for the others.
2. A helper category is added to provide helpers functions for creating common builders.

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.
