1D tile span support for depth/stencil/color/textures
Z and stencil buffers are always tiled, so this fixes
sw access to Z and stencil buffers. color and textures
are currently linear, but this adds span support when we
implement 1D tiling.
This fixes the text in progs/demos/engine and progs/tests/z*

Noticed by rnoland on IRC.

We use t->bo for dri1 since r600 uses CS for dri1.
|
|
if we have a BO here it means TFP and we should have set it
up already.
tested by b0le on #radeon

Caused by some weird logic regarding the __WIN32__ define which made
the finite definition dependent on the header include order.
|
|
Shaders and IB need to be updated and allocated before
calling validatebuffers.

Fixes #22741

Mostly fixes progs/demos/lodbias when MESA_TEX_PROG=1. But the LOD still
seems off by -1 or so.
May be an issue with the params passed to _swrast_compute_lambda()

seems to work here ...

In get_array_bounds we were previously defining a user buffer sized as
(nr_vertices * stride). The trouble is that if the vertex data
occupies less than stride bytes, the extra tailing (stride - size)
bytes may extend outside the memory actually allocated by the app and
caused a segfault.
To fix this, define a the buffer bounds to be:
ptr .. ptr + (nr-1)*stride + element_size

This should help to work around bugs 24083 and 23670.

This was introduced with commit 92d7ed8a20d4a018ce5324e6537ae7b478b9e5bf.
It causes rendering of stray polygons (with sw rendering at least) when
running the OGL Distilled / Picking demo (click on an object).
This needs additional debugging to fix/restore.
Found one suspect thing: in _tnl_draw_prims() there's some mixed signed/
unsigned arithmetic/comparing at line 422 that may be incorrect.

If the 'end' index is out of bounds issue a warning as before. But instead
of just no-op'ing the draw call, examine the actual array indices to see
if they're OK. If the max array index is out of bounds, issue another
warning and no-op the draw call. Otherwise, draw normally. This is a
debug build-only feature since it could impact performance.
This "fixes" the missing torus in the OGL Distilled / Picking demo.

If arx and ary are equal, we still want to choose from one of them,
and not arz.
This is the same as Michal's softpipe fix.

- max texture size is 8k, but mesa doesn't support
that at the moment.
- attempt to set shader limits to what the hw actually
supports
- clean up some old r300 cruft
- no need to explicitly disable irqs. This is fixed
in the drm now.
