Espresso test for loopback video quality testing

Update the AppRTCMobileTestStubbedVideoIO test to run on
phones without Internet connection. This is done by bringing up
a local instance of AppRTC on the Linux machine connected to
the Android device.

Running this test will need the webrtc.DEPS solution to be configured
for the checkout, since that will pull down the precompiled AppRTC
package that is needed.

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.
