9 years agogbm: Search LIBGL_DRIVERS_PATH if GBM_DRIVERS_PATH is not set

gbm: Search LIBGL_DRIVERS_PATH if GBM_DRIVERS_PATH is not set

The GBM_DRIVERS_PATH environment variable is not documented, and only
used to set the location of gbm drivers, while LIBGL_DRIVERS_PATH is
used for everything else, and is documented.

Generally this split leads to confusion as to why gbm doesn't work.

This patch will read LIBGL_DRIVERS_PATH as a fallback if
GBM_DRIVERS_PATH is not set.

The comments clearly indicate that using LIBGL_DRIVERS_PATH is
preferred over GBM_DRIVERS_PATH.

v2: - Use GBM_DRIVERS_PATH as a fallback
v3: [jordan.l.justen@intel.com] - Make LIBGL_DRIVERS_PATH the fallback

i965: Fix z_offset computation in intel_miptree_unmap_depthstencil()

The bug is triggered by using glTexSubImage2d() with GL_DEPTH_STENCIL
as base internal format and non-zero x, y offsets. Currently x, y
offsets are ignored while updating the texture image.

Fixes Khronos GLES3 CTS tests:
npot_tex_sub_image_2d
npot_tex_sub_image_3d
npot_pbo_tex_sub_image_2d
npot_pbo_tex_sub_image_2d

Fixes the 11 regressions caused in framebuffer_blit tests in
Khronos GLES3 CTS tests:

Original patch reduced the instruction count but had no performance
benefits. So, it's safe to revert it without causing any performance

i915: Fix up intelInitScreen2 for DRI3

Commit 442442026eb updated both i915 and i965 for DRI3 support,
but one check in intelInitScreen2 was missed for i915 causing crashes

This commit "mesa: fix packing of float texels to GL_SHORT/GL_BYTE" replaced *_TO_BYTE to *_TO_BYTE_TEX because *_TO_FLOAT_TEX are used to unpack the texels to floats.
In this case *_TO_FLOATZ in function extract_float_rgba also should be replaced to *_TO_FLOAT_TEX. Underline that these macros automatically preserve zero when converting.

The regression was observed on 3 oglconform tests:
