This copies the files for the GLU tesselator from Mesa. The Mesa code is based on the original SGI code and is released under a BSD license. The memalloc.h header has been replaced with one that forces the code to use g_malloc and friends. The rest of the files are not altered from the original so it should be possible to later upgrade the files by simply overwriting them. There is a tesselator.h header which is expected to be included by rest of Cogl to use the tesselator. This contains a trimmed down version of glu.h that only includes parts that pertain to the tesselator. There is also a stub glu.h in the GL directory which is just provided so that the tesselator code can include <GL/gl.h> without depending on the system header. It just redirects to tesselator.h
