Android VideoRendererGui: Make deep copy of incoming texture frames

VideoRendererGui may need to render incoming frames multiple times. We currently call VideoRenderer.renderFrameDone() while we still hold references to the OES texture. This CL makes a deep copy of the OES texture before calling renderFrameDone(). This will truly release the dependency to the incoming frame, so that video textures sources can rely on the renderFrameDone() callback.

This CL is a part of the plan in https://codereview.webrtc.org/1357923002/.

The texture copy doesn't cause any measurable performance difference on a Nexus 5 using VideoRendererGui in a AppRTCDemo loopback call.

BUG=webrtc:4993
TEST=Revert "Enable SurfaceViewRenderer for AppRTCDemo" https://codereview.webrtc.org/1356603004/ and try AppRTCDemo.

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.
