Build the new sources, plug the new functions into the dispatch table,
implement display list support. And enable extension in the gallium
state tracker.
gl_texture_object contains an instance of this type for the regular
texture object sampling state. glGenSamplers() generates new instances
of gl_sampler_object which can override that state with glBindSampler().
Fixes issues in e.g. nexuiz (desertfactory) or supertuxkart that
look like lighting bugs.
They're not visible with the software rasterizers because their
notion of linear interpolation seems to be different from that
of nv50/nvc0.
This reverts commit 437c748bf5.
The commit is wrong for several reasons. One of them is when we grab
a new buffer, we should update all the states it is bound in,
including all parallel contexts. I don't think this is even doable.
The correct solution would be upload data via a temporary buffer and
do resource_copy_region to the original one.

Add Cygwin platform-specific settings and drivers to build for dri driver:
- by default, disable direct rendering.
- if direct rendering is enabled, the swrast dridriver is the only one it's
sensible to try to build (this doesn't work at the moment as additional patches
are required to build a libGL which can load just swrast without the DRM headers,
even though there's no actual functional dependency)

The theory here was to detect a temporary variable used within a loop,
and avoid considering it live across the entire loop. However, it was
overeager and failed when the first definition of the variable
appeared within the loop but was only conditionally defined.
Fixes glsl-fs-loop-redundant-condition.
Otherwise min_lod can potentially be larger than the clamped max_lod. The
code that follows will swap min_lod and max_lod in that case, resulting in a
max_lod larger than MAX_LEVEL.

Base level and min LOD aren't equivalent. In particular, min LOD has no
effect on image array selection for magnification and non-mipmapped
minification.
