The classic OSMesa renders directly into user memory using
src/mesa/swrast, while gallium OSMesa renders using softpipe or llvmpipe
and copies out at glFlush() time. This would make gallium look like a
worse choice for OSMesa, except that swrast is:
1) Painfully slow to render compared to llvmpipe
2) Incorrect at derivatives
3) Limited to GL 2.1 instead of GL 4.6
In my survey of OSMesa users, debian was the remaining holdout with
classic OSMesa in use on hurd and some rare non-LLVM-supported
architectures (sh4, alpha, etc.). As of today, they've switched to
softpipe-based gallium OSMesa for them.
To prevent people from running the wrong OSMesa (to the extent that
running OSMesa can ever be the right thing), delete the classic
version.

The idea of having a single file containing the ToC is not really how
things are done in Sphinx, and kinda makes it harder to structure
documentation more naturally. This was just something I did to mirror
what we used to do for the old HTML-only version of the docs, to ease
the transition and to de-clutter index.rst.
Now that the transition is far behind us, and index.rst is much cleaner,
we can finally start inlining this.
In the long run, I expect most of these to be moved to separate "chapter
articles" that summarize what these topics are, and thus disappear from
here.

This documentation is severely out of date anyway, and as it doesn't

Rather than hard-code a list of all the format
modifiers supported by any gallium driver and the
number of aux planes they require in the dri state
tracker, add a screen proc that queries the number
of planes required for a given modifier+format
pair.
Since the only format modifiers that require
auxiliary planes currently are the iris driver's
I915_FORMAT_MOD_Y_TILED_CCS,
I915_FORMAT_MOD_Y_TILED_GEN12_RC_CCS, and
I915_FORMAT_MOD_Y_TILED_GEN12_MC_CCS, the absence
of the screen proc implies zero aux planes for all
of the screen's supported modifiers. Hence, when
a driver does not expose the proc, derive the
number of planes directly from the format.

This causes our TGSI to use far more temps, since NTT is currently not
releasing temps from registers. On the other hand, this interpreter is
already spectacularly slow, and if we wanted to go fast we should probably
write a scalar NIR intrepeter.
For now, using NTT means that we test that codepath in preparation for
switching TGSI-consuming HW drivers over, so that we can eventually
garbage collect st_glsl_to_tgsi.
As this is a major restructuring, there are some impacts on piglit:
- Several tests start assert failing about 64-bit NIR registers for temp
arrays not getting split to vec2s:
- fs-frexp-dvec4-variable-index.shader_test
- arb_gpu_shader_fp64/uniform_buffers/{vs,fs,gs}-array-copy.shader_test
- arb_gpu_shader_int64/execution/indirect-array-two-accesses.shader_test
- dEQP-GLES31.functional.primitive_bounding_box.wide_points.global_state.vertex_geometry_fragment.fbo_bbox_larger
starts crashing depending on various bits of state (previous tests run
before it, presence of valgrind, presence of glib's memcheck). Doesn't
seem really NTT-specific, added to flakes list with other GS flakes.
- Almost 200 fp64/int64-related tests start passing, mostly around i/o loayout.

On some systems it is problematic to have the shader cache enabled
by default. This adds a build option to support the disk cache but
keep it disabled unless the environment variable
MESA_GLSL_CACHE_DISABLE=false.
For example, on Chrome OS, Chrome already has it's own shader
disk cache implementation so it disables the mesa feature. Tests
do not want the shader disk cache enabled because it can cause
inconsistent performance results and the default 1GB for the
disk cache could lead to problems that require more effort to
work around. The Mesa shader disk cache is useful for VMs though,
where it is easy to configure the feature with environment
variables. With the current version of Mesa, Chrome OS would need
to have a system-wide environment variable to disable the disk
cache everywhere except where needed. More elegant to just build
Mesa with the cache feature disabled by default.
