Remove demos that have moved to git+ssh://git.freedesktop.org/git/mesa/demos.

The remaining programs are ones I've had difficulty finding a build
environment for to make the build system or are unit tests that should
probably live next to their code instead.  Hopefully people can bring
over the build for remaining pieces they care about.

-/*
- * GLUT demonstration of texturing with specular highlights.
- *
- * When drawing a lit, textured surface one usually wants the specular
- * highlight to override the texture colors.  However, OpenGL applies
- * texturing after lighting so the specular highlight is modulated by
- * the texture.
- *
- * The solution here shown here is a two-pass algorithm:
- *  1. Draw the textured surface without specular lighting.
- *  2. Enable blending to add the next pass:
- *  3. Redraw the surface with a matte white material and only the
- *     specular components of light sources enabled.
- *
