In particular, make sure the code is at least compiled on little endian
systems.

This would actually fail to compile when PIPE_ARCH_BIG_ENDIAN is defined.

E.g. when the internal format was RGBA16F and the source was RG, it would use
memcpy.

I hit this when testing RV350, which lacks RGB10_A2 render target
support. It had been missed when implementing the format and probably
unused by anything else too.
Not applicable to 7.10.

Doesn't cause any piglit regression and passes the fbo-draw-buffers-blend

"st/mesa: check image size before copy_image_data_to_texture()" caused
a regression in piglit fbo-generatemipmap-formats test on all gallium drivers.
Level 0 for NPOT textures will not match minified values, so don't do this
check for level 0.

the provoking vertex doesn't apply to quad/strip/polygon.

the hw does neg after abs, so don't neg the source in the ABS instruction case.

In the initial code if we had nothing in the vector slots r would
never get reset to 0, so we'd fail to compile shaders, after the previous
commit this would happen for the LIT tests. When I fixed that we did a lot
of unnecessary loops through all the vector states when we had no vector
slots filled. So this patch optimises thing for the scalar only state.
This fixes the 3 LIT piglit tests on r600g.

In the R600 ISA document:
Section 4.7.5 Cycle restrictions for the ALU.trans states that
PV/PS have cycle restrictions wrt constants.
This is part of a fix for the LIT tests

This came from reading what swrast does, and 965 now behaves the same
and gallium appears to as well.

Fixes a bug in Trine where fragment.color would write
FRAG_RESULT_COLOR (which is interpreted by drivers as being the "write
this to all color buffers" option) instead of FRAG_RESULT_DATA0 (just
the first target).
Fixes piglit ATI_draw_buffers/arbfp-no-index.

Still doesn't fix texwrap.

This extension support consists of replacing
"gl_texture_obj->Sampler." with "_mesa_get_samplerobj(ctx, unit)->".
One instance of referencing the texture's base sampler remains in the
initial miptree allocation, where I'm not sure we have a clear
association with any texture unit.
Tested with piglit ARB_sampler_objects/sampler-objects.

Since we lack hardware support for it, this is a simple matter of
checking _mesa_check_conditional_render at the entrypoints, and
suppressing it for the metaops where it doesn't apply.

The NV_conditional_render spec calls out specific operations that
conditional rendering applies to, which doesn't include these.
Fixes NV_conditional_render/generatemipmap on swrast.

Tested with rgtc-teximage-0[12].
EXT_texture_compression_rgtc/fbo-generatemipmap-formats fails in NPOT
just like S3TC does.

This assertion doesn't make any sense to me -- the convertFormat is
already something valid (tested above), and the BaseFormat dictated by
convertFormat doesn't matter to the function about to be called (it's
the datatype/comps that were pulled out of convertFormat).
Fixes assertion failure in
GL_EXT_texture_compression_rgtc/fbo-generatemipmap-formats
(still has a rendering failure in NPOT like S3TC does).

We were falling through to the default R8 and RG88 formats instead of
compressing when possible. Noticed by swrast fbo-blending-formats
actually doing rendering.

We are now able to declare global critical sections through other
