(cherry picked from commit 7f6d2754d586545ab6c970acffdd897294879039)

The code was walking over the regs of pairs of attributes and checking
whether the attribute with a given reg index had point sprite enabled.
So the point sprite setup code was rarely even getting executed.
Instead, we need to determine which channels of a reg need point
sprite coordinate replacement. In addition, it was multiplying the
attribute by 1/w, when it's supposed to cover (0, 1) in each direction
regardless of w, and it wasn't filling in the Z and W components of
the texcoord as specified.
Fixes piglit point-sprite and the spriteblast demo. Bug #24431, #22245.

This would be triggered by use of sqrt() along with control flow.
Fixes piglit-fs-sqrt-branch and a bug in Yo Frankie!.

The bad response length would hang the GPU with a masked sample in a
shader using control flow. For 8-wide, the response length is always
4, and masked slots are just not written to. brw_wm_glsl.c already
allocates registers in the right locations.
Fixes piglit glsl-fs-bug25902 (fd.o bug #25902).

The Makefile should eventually be fixed to stop building tarballs if
one of the individual calls to tar fails.

These seem to be documented in
<http://www.svgopen.org/2003/papers/RasterOperationsUsingFilterElements/index.html>.

use cso_set_fragment_sampler_views instead of cso_set_sampler_textures

If flush happens inside radeonRefillCurrentMaRegion the last dma buffer would
be unmapped twice. Unmapping buffer when moving buffer to wait list fixes the
mapping error.

GALLIUM_DRIVER is being used in many other places, and it easier to
memorizing and understand than all the GALLIUM_NO_XXX.

changes arguments of util_blit_pixels_tex and util_gen_mipmap to
struct pipe_sampler_view * instead of struct pipe_texture *.

This branch already seems to have the nv50_tex.c fix.

The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.

No idea if this is the correct fix, but it makes it work again at least.

We were never returning -1 as a result. This fixes some inverted/flipped
faces with cube mapping.
|
|
Sampler views already hold references to those.
|
|
When min_lod==max_lod we don't need to go through all the work of
computing the lod from partial derivatives. This is hit by the mipmap
generation utility code.
|
|
|
|
Use the LOD value to determine whether to use the minification vs.
magnification filter.
All mipmap sampling modes work now.

LLVMBuildFPTrunc() should be used for double->float conversion, not
float->int conversion.
There should be a better way to compute floor(), ceil(), etc that doesn't
involve float->int->float conversion.

This creates a cleaner winsys and drop the simple screen stuff.
It makes r300g use pb_bufmgr structs.
It also tries to avoid overheads from mapping too often.
v5: clean warnings
v6: break out of cache check on first buffer - since most likely
the first busy one implies all after it are busy.
v7: cleanup a bit
v8-merged: drop cman for now to just get all the interface changes in first.
rework to changes that happened upstream
