This CL adds support for unittests of the AudioDeviceModule on Android using both Java and C++. The new framework uses ::testing::TesWithParam to support both Java-based audio and OpenSL ES based audio. However, given existing issues in our OpenSL ES implementation, the list of test parameters only contains Java in this first version. Open SL ES will be enabled as soon as the backend has been refactored. It also: - Removes the redundant JNIEnv* argument in webrtc::VoiceEngine::SetAndroidObjects(). - Modifies usage of enable_android_opensl and the WEBRTC_ANDROID_OPENSLES define. - Adds kAndroidJavaAudio and kAndroidOpenSLESAudio to AudioLayer enumerator. - Fixes some bugs which were discovered when running the tests.
