Split peerconnection_jni.cc into separate files.
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.
