From Wang Rui, new native binary/ascii format infrastructure and wrappers.

From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg

src/osgWrappers/serializers/osg/AnimationPathCallback.cpp
