which is a gl_vertex_attrib_array structure, not a gl_client_array.

The offsets of all fields happened to be the same in both structures, at
least on x86_64.  "Size," "Type," and "Stride" are obviously the same:
both structures start with the same fields, in the same order.

"Enabled" is dicier: there are different fields before it in both
structures, including pointer sized values which might need special
alignment.

mesa: Remove some dead helper functions.

Dead since the _MaxElement removal, but these functions seemed generally
applicable, so I decided to remove them in a separate patch.

vc4: Compute max_index instead of trusting the rest of userspace.

max_index was coming from either the user telling us as part of
glDrawRangeElements, or from an incidental calculation as part of some
sort of primitive conversion fallback.  Sometimes, it was just set to the
default "I don't know" ~0 value.

If it wasn't set to the actual max index, then the kernel would reject the
draw call for allowing out-of-bounds VBO reads.  So, compute the max index
from the sizes of the VBOs, which isn't too expensive (unlike mapping and
reading the index buffer) and is reliable.

Fixes piglit vao-element-array-buffer.

vc4: Move shader record setup before the draw call.

The flush only happens after both are written, so we can do them in either
order.  This will let me compute max_index during the shader record setup.

vc4: Add support for gl_PointCoord.

Fixes piglit glsl-fs-pointcoord, point-sprite, and fbo-gl_pointcoord.

vc4: Add support for point size setting.

This is the support for both the global and per-vertex modes.

vc4: Add support for line width setting.

I don't see piglit tests for it, but this should be better than not
emitting it at all.

vc4: Actually add support for polygon offset.

Setting the bit without setting the offset values is kind of useless.
Fixes piglit polygon-offset (but not polygon-mode-offset).

vc4: Fix swapped 565 dithering versus no-dithering render configs.

Fixes many 565 piglit tests (like fbo-generatemipmap-formats) that weren't
expecting dithering.

vc4: Add support for alpha test.

Fixes most of piglit fbo-alphatest-formats (but not RGB565/332).

freedreno/a3xx: initial texture border-color

Still some open questions.. and at any rate, no additional piglit passes
due to various wrap modes that we need to emulate in at least some
cases :-(

But it does fix some mystery page-faults.. So add some comments in the
code where there are things that we need to emulate or do more r/e, and
push as-is.
