mesa: allow variable indexing into the predefined uniform variable arrays

This allows code such as "vec4 a = gl_LightSource[i].ambient;" to work.

When a built-in uniform array is indexed with a variable index we need to
"unroll" the whole array into the parameter list (aka constant buffer) because
we don't know which elements may be accessed at compile-time.  In the case of
the gl_LightSource array of size [8], we emit 64 state references into the
parameter array (8 elements times 8 vec4s per gl_LightSourceParameters
struct).

Previously, we only allowed constant-indexed references to uniform arrays
(such as gl_LightSource[2].position) which resulted in a single state reference
being added to the parameter array, not 64.  We still optimize this case.

Users should be aware that using "gl_LightSource[i].ambient" in their shaders
is a bit expensive since state validation will involve updating all 64
light source entries in the parameter list.

Gallium: fix for conform test

The following construction in util_surface_copy() in
gallium/auxiliary/util/u_rect.c, introduced in commit
d177c9ddda2c452cf7d6696d89cf4458ef986f98, incorrectly inverts
the Y coordinate in the last parameter to pipe_copy_rect().

      /* If do_flip, invert src_y position and pass negative src stride
*/
      pipe_copy_rect(dst_map,
                     &dst->block,
                     dst->stride,
                     dst_x, dst_y,
                     w, h,

                     do_flip ? -(int) src->stride : src->stride,
                     src_x,
                     do_flip ? w - src_y : src_y);

The intention is to start at the last Y coordinate line and move
backwards, in the case of a flip; in that case, the correct
calculation is "src_y + h - 1", not "w - src_y".

This fixes a Gallium assertion failure in the conformance tests:

      u_rect.c:65:pipe_copy_rect: Assertion `src_y >= 0' failed.
