Updated Nintendo DS support

Frank Zago

This patch updates the DS port:
- do not use the now removed compat layer.
- integrate parts of libgl2D since I got permission from the author, and thus
removed an external dependancy,
- a few bugs fixes.

Now, the textures should be completely supported, except reading from them
which doesn't makes sense to have on the DS. Sound is still not supported.

If someone else wants to work on the missing pieces, feel free.
