egl: let each platform decided how to handle LIBGL_ALWAYS_SOFTWARE

My refactor in 47273d7312cb5b5b6b0b9 missed this early return; because
of it, setting UseFallback one layer above actually prevented the
software path from being used.

Remove this early return and let each platform's dri2_initialize_*()
decide what it can do with the LIBGL_ALWAYS_SOFTWARE restriction.

egl: link libEGL against the dynamic version of libglapi

Note: the following happens only when using slibtool.
Since this is a very serious breakage, we will keep the workaround until
a better solution is available.

DRI modules store the address of the dispatch table in a TLS variable,
_glapi_tls_Dispatch.

Changes to the way libEGL is built in d884d8d0077c16d459b1 resulted in
it being statically linked against libglapi, and thus containing its own
copy of _glapi_tls_Dispatch. The result was that some applications would
fail to work (e.g. deqp-egl, which dynamically loads libEGL), due to the
DRI module storing the dispatch table address in one copy of
_glapi_tls_Dispatch, and libEGL obtaining the address from another copy
of the variable.

intel/fs/bank_conflicts: Use posix_memalign() instead of overaligned new to obtain vector storage.

The weight_vector_type constructor was inadvertently assuming C++17
semantics of the new operator applied on a type with alignment
requirement greater than the largest fundamental alignment.
Unfortunately on earlier C++ dialects the implementation was allowed

types even if the C++17 dialect wasn't active, which is likely the

radv: fix issue with multisample positions and interp_var_at_sample.

This fixes vmfaults seen on vega with:
dEQP-VK.pipeline.multisample_interpolation.sample_interpolate_at_single_sample_.128_128_1.samples_1

These were caused by the don't allocate cmask but it was just accidental.

The actual problem was the shader was trying to get the sample positions from
a buffer, but the buffer was never getting configured to contain them, as the
previous shader never needed them.

glsl: disable vec3 packing/splitting in tfb separate mode

This fixes a varying packing issue when using transform feedback in
GL_SEPARATE_ATTRIBS mode.  By time we get to linking, we already
know that the number of feedback attributes is under the
GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS limit so packing isn't
as critical.  In fact, packing/splitting vec3 attributes can cause
trouble because splitting effectively creates another TFB output
which can exceed device limits.  So, disable vec3 packing when it's
not needed to avoid that issue.

Fixes the Piglit ext_transform_feedback-separate test on VMware
driver.

nvc0/ir: change textureGrad to always use lane 0 as the tex origin

Thanks to Karol Herbst for the debugging / tracing work that led to this
change.

Move to using lane 0 as the "work" lane for the texture. It is unclear
why this helps, as that computation should be identical to doing it in
the "correct" lane with the properly adjusted quadops.

In order to be able to use the lane 0 result, we also have to ensure
that lane 0 contains the proper array/indirect/shadow values.

This applies to Fermi and Kepler. Maxwell+ may or may not need fixing,
but that lowering logic is separate.

broadcom/vc5: Add missing setting of the UIF XOR disable flag in textures.

Most piglit textures happened to work out by RGBW not changing in that
bit, but it did cause failures in RGBA16F fbo-generatemipmap-formats.

broadcom/vc5: Clean up the comment and code around level 0 UIF.

I wrote this early in driver development, and our UIF handling is much
better now.

broadcom/vc5: Simplify the tiling calculations.

The mb_tile_layout table was just the utile_w/h times two, so reuse the
utile code instead.

broadcom/vc5: Return the depth in all components of depth textures.

Apparently gallium's u_blitter wants depth from at least the .z component,
and other swizzling appears to apply on top of that.  Fixes
fbo-generatemipmap-formats failures with depth formats.

broadcom/vc5: Enable decompressing RGTC for desktop GL support.

This matches freedreno's behavior.

broadcom/vc5: Use u_transfer_helper for MSAA mappings.

broadcom/vc5: Start adding support for rendering to Z32F_S8X24_UINT.

There may be some more RCL work to be done (I think I need to split my Z/S
stores when doing separate stencil), but this gets piglit's "texwrap
GL_ARB_depth_buffer_float" working.

v2: Unwrap the z32f_wrapper before calling the helper, rather than having
    the helper have a callback.
v3: Rebase on Rob Clark's u_transfer_helper instead
