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.

- * Test GL_ARB_draw_buffers2, GL_ARB_draw_buffers, GL_EXT_framebuffer_object
- * and GLSL's gl_FragData[].
- *
- * We draw to two color buffers and show the left half of the first
- * color buffer on the left side of the window, and show the right
- * half of the second color buffer on the right side of the window.
- *
- * Different color masks are used for the two color buffers.
- * Blending is enabled for the second buffer only.
