We were counting uniforms located in UBOs against the default uniform block limit, while not doing any counting against the specific combined limit. Note that I couldn't quite find justification for the way I did this, but I think it's the only sensible thing: The spec talks about components, so each "float" in a std140 block would count as 1 component and a "vec4" would count as 4, though they occupy the same amount of space. Since GPU limits on uniform buffer loads are surely going to be about the size of the blocks, I just counted them that way. Fixes link failures in piglit arb_uniform_buffer_object/maxuniformblocksize when ported to geometry shaders on Paul's GS branch, since in that case the max block size is bigger than the default uniform block component limit.
