atidx10caps + reserved_color_varyings patch

I decided to looking into the varyings again since the fixed catalyst 9.6
release is upon  us soon. Looking through the wine logs and source I realized
that I tested the test program wrong. I was setting both fragment and vertex
shaders to use an array of 12 varyings in order to compile successfully, but I
only needed to set 12 in the fragment shader.

So testing again I found out that gl_FrontColor and gl_FrontSecondaryColor are
part of the total 64 varyings that can be used. For example, wine is setting an
array of varying vec4 IN[15] (-1 for clip varyings) then uses them all and then
ends with gl_FrontColor and gl_FrontSecondaryColor which is 17 varyings for
ATI. 

I fxied it by reserving 2 varyings in the vec4_varyings function and combined
it in with the opengl capabilities fixes, but I'll clean it up and submit it
without the opengl cap fixes if it looks alright.
