MB: Copy MB from Chromium repo

Essentially a copy of https://codereview.chromium.org/2299953002/
plus changes to WebRTC's license, changed OWNERS and additional
MB updates up to Chromium revision http://crrev.com/f1e2718a3ff.

The PRESUBMIT.py check was updated to use the existing
webrtc/build/mb_config.pyl to avoid breaking bots (that have
this path hardcoded).

This replaces the previously symlinked MB, which already
runs validation of the WebRTC configs as part of
webrtc/build/PRESUBMIT.py.

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. This page is maintained by the Google Chrome team.

Development

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