For now: java_helpers - JNI convenience functions etc. Can in theory be moved to libjingle / webrtc general one day. classreferenceholder - app/webrtc specific Java class loader. androidvideocapturer_jni - the jni part of the video capturer I added. peerconnection_jni - all the rest. This also move all jni specifics into ns webrtc_jni to avoid naming collision.
