fixed API names in JNI to conform with org.wikimedia.analytics.dclassjni  package name set in kraken repo. Removed printf lines which were meant for debugging. removed some of the javadoc comments that were causing problems because of old DClassParsedResult class which doesn't exist anymore(we're retuning a Map<String, String> now instead). Modified Makefile.am to create a libdclassjni.so only now which has bundled inside it all the needed symbols. Stay tuned for push on kraken repo.  Also renamed org.wikimedia.analytics.dclass_jni to org.wikimedia.analytics.dclassjni
