glsl: Remove unused total_attribs_size variable.

Accidentally left behind by my previous patch.

glsl: Handle attribute aliasing in attribute storage limit check.

In various versions of OpenGL and GLSL, it's possible to declare
multiple VS input variables with aliasing attribute locations.

So, when computing the storage requirements for vertex attributes,
we can't simply add up the sizes.  Instead, we need to look at the
enabled slots.

This patch begins tracking which attributes are double types that
are larger than 128-bits (i.e. take up two vec4 slots).  We then
count normal attributes once, and count the double-size attributes
a second time.

Fixes deQP functional.attribute_location.bind_aliasing.max_cond_* tests
on i965, which regressed with commit ad208d975a6d3aebe14f7c2c16039ee20.

No Piglit changes on llvmpipe (which actually supports dvecs).

mesa/readpixels: check strides are equal before skipping conversion

The CTS packed_pixels test checks that readpixels doesn't write
into the space between rows, however we fail that here unless
we check the format and stride match.

This fixes all the core mesa problems with CTS packed_pixels

gallium/util: fix returning empty box for rectangle intersection

These functions deal with inclusive coordinates, hence a 0/0/0/0 rect
returned when there's no intersection doesn't actually represent an empty
rectangle. Hence return 0/-1/0/-1 instead.
This fixes some problems in llvmpipe with empty scissor rects (which up
to now didn't really matter because while the intersect test returned the
wrong result all pixels were scissored away later anyway).

gallium/util: return FALSE for intersection if there's empty rectangles

It isn't really obvious if intersection test should take into account empty
rectangles or if the caller should do it. But it looks like most callers
actually verified one of the rects but not the other, but since correctly
returning an empty rect that other rect could actually be empty leading to
more bugs. Hence just verify both rects for emptyness in the intersection
test itself which makes the code easier in the caller (though it will be
slower if the caller knows the rectangles are non-empty).
