Copied libutil and libtess implementations in form Mesa 7.9/src/glu into the src/osg/glu, changed extensions from .c to .cpp and got compiling as C files as part of the osg core library. Updated and cleaned up the rest of the OSG to use the new internal GLU.

#include <osg/GL>
Changed the GLU_TESS_CALLBACK in an attempt to avoid compile problems under OSX.

Introduced osg namespace to new local GLU functions

Introduced new gluScaleImage function that uses a PixelStorageModes structure to pass in details on image packing, rather than relying upon glGet's to get the values.
