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.

-** blendeq.c - Demonstrates the use of the blend_minmax, blend_subtract,
-**    and blend_logic_op extensions using glBlendEquationEXT.
-**
-**    Over a two-color backround, draw rectangles using twelve blend
-**    options.  The values are read back as UNSIGNED_BYTE and printed
-**    in hex over each value.  These values are useful for logic
-**    op comparisons when channels are 8 bits deep.
