I won't apply on master.
I just removed jni_LockAndGetAndroidSurface and vout_android_surf  in a
recent commit.
And I added this new function: jni_AndroidJavaSurfaceToNativeSurface.
But It should be easy to merge since it'll work with your new
android_surface struct.

Why not having EventHandler an object inside LibVLC ?
So, To get the EventHandler: mLibVlc.getEventHandler() (from java and
native).
That way, you can get ride of all hashmap and you don't have to call
EventHandler methods with an instance of LibVlc.
