Magnus Jedvert 80cf97cddd Android rendering: Move common EGL and GL functions to separate classes
This CL does not make any functional changes. The purpose is to extract some common code that is needed for texture capture and texture encode.

This CL does the following changes:
* Move common EGL functions from org.webrtc.MediaCodecVideoDecoder to org.webrtc.EglBase.
* Move common GL functions from org.webrtc.VideoRendererGui to org.webrtc.GlUtil and org.webrtc.GlShader.
* Remove unused call to surfaceTexture.getTransformMatrix in YuvImageRenderer.
* Add helper functions rotatedWidth()/rotatedHeight() in VideoRenderer.I420Frame.

This directory holds a Java implementation of the webrtc::PeerConnection API, as
well as the JNI glue C++ code that lets the Java implementation reuse the C++
implementation of the same API.

To build the Java API and related tests, build with 
OS=linux or OS=android and include
build_with_libjingle=1 build_with_chromium=0
in $GYP_DEFINES.

To use the Java API, start by looking at the public interface of
org.webrtc.PeerConnection{,Factory} and the org.webrtc.PeerConnectionTest.

To understand the implementation of the API, see the native code in jni/.

An example command-line to build & run the unittest:
cd path/to/trunk
GYP_DEFINES="build_with_libjingle=1 build_with_chromium=0 java_home=path/to/JDK" gclient runhooks && \
    ninja -C out/Debug libjingle_peerconnection_java_unittest && \
    ./out/Debug/libjingle_peerconnection_java_unittest
(where path/to/JDK should contain include/jni.h)

During development it can be helpful to run the JVM with the -Xcheck:jni flag.
