222b85328e mesa: replace most occurrences of getenv() with os_get_option()
The standard way to query options in mesa is `os_get_option()` which
abstracts platform-specific mechanisms to get config variables.

However in quite a few places `getenv()` is still used and this may
preclude controlling some options on some systems.

For instance it is not generally possible to use `MESA_DEBUG` on
Android.

So replace most `getenv()` occurrences with  `os_get_option()` to
support configuration options more consistently across different
platforms.

Do the same with `secure_getenv()` replacing it with
`os_get_option_secure()`.

The bulk of the proposed changes are mechanically performed by the
following script:

-----------------------------------------------------------------------
  #!/bin/sh

  set -e

  replace() {

    # Don't replace in some files, for example where `os_get_option` is defined,
    # or in external files
    EXCLUDE_FILES_PATTERN='(src/util/os_misc.c|src/util/u_debug.h|src/gtest/include/gtest/internal/gtest-port.h)'

    # Don't replace some "system" variables
    EXCLUDE_VARS_PATTERN='("XDG|"DISPLAY|"HOME|"TMPDIR|"POSIXLY_CORRECT)'

    git grep "[=!( ]$1(" -- src/ | cut -d ':' -f 1 | sort | uniq | \
      grep -v -E "$EXCLUDE_FILES_PATTERN" | \
      while read -r file;
      do
        # Don't replace usages of XDG_* variables or HOME
        sed -E -e "/$EXCLUDE_VARS_PATTERN/!s/([=!\( ])$1\(/\1$2\(/g" -i "$file";
      done
  }

  # Add const to os_get_option results, to avoid warning about discarded qualifier:
  #   warning: initialization discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
  # but also errors in some cases:
  #   error: invalid conversion from ‘const char*’ to ‘char*’ [-fpermissive]
  add_const_results() {
    git grep -l -P '(?<!const )char.*os_get_option' | \
      while read -r file;
      do
        sed -e '/^\s*const/! s/\(char.*os_get_option\)/const \1/g' -i "$file"
      done
  }

  replace 'secure_getenv' 'os_get_option_secure'

  replace 'getenv' 'os_get_option'

  add_const_results
-----------------------------------------------------------------------

After this, the `#include "util/os_misc.h"` is also added in files where
`os_get_option()` was not used before.

And since the replacements from the script above generated some new
`-Wdiscarded-qualifiers` warnings, those have been addressed as well,
generally by declaring `os_get_option()` results as `const char *` and
adjusting some function declarations.

Finally some replacements caused new errors like:

-----------------------------------------------------------------------
../src/gallium/auxiliary/gallivm/lp_bld_misc.cpp:127:31: error: no matching function for call to 'strtok'
  127 |          for (n = 0, option = strtok(env_llc_options, " "); option; n++, option = strtok(NULL, " ")) {
      |                               ^~~~~~
/android-ndk-r27c/toolchains/llvm/prebuilt/linux-x86_64/bin/../sysroot/usr/include/string.h:124:17: note: candidate function not viable: 1st argument ('const char *') would lose const qualifier
  124 | char* _Nullable strtok(char* _Nullable __s, const char* _Nonnull __delimiter);
      |                 ^      ~~~~~~~~~~~~~~~~~~~
-----------------------------------------------------------------------

Those have been addressed too, copying the const string returned by
`os_get_option()` so that it could be modified.

In particular, the error above has been fixed  by copying the `const
char *env_llc_options` variable in
`src/gallium/auxiliary/gallivm/lp_bld_misc.cpp` to a `char *` which can
be tokenized using `strtok()`.

ddf2aa3a4d build: avoid redefining unreachable() which is standard in C23
In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>

See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in

And this causes build errors when building for C23:

-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
                 from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
  123 | #define unreachable(str)    \
      |         ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
  456 | #define unreachable() (__builtin_unreachable ())
      |         ^~~~~~~~~~~
-----------------------------------------------------------------------

So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.

Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.

This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.

All the instances of the macro, including the definition, were updated
with the following command line:

  git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
  while read file; \
  do \
    sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
  done && \
  sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

355b96413d egl/wayland: Move bind_wayland_display to legacy build option
Similar to how support for X11's DRI2 protocol was deprecated in 24.2,
begin deprecating EGL_WL_bind_wayland_display (including
eglBindWaylandDisplayWL et al) by moving it behind a legacy-wayland
build option.

This extension was originally created in a pre-dmabuf world, where we
didn't have a universally-accepted way of exchanging buffers between
client and compositor, or even really the ability to describe formats
and modifiers universally.

Since then, the world has settled on dmabuf with DRM FourCC and
modifiers. We've had the zwp_linux_dmabuf_v1 protocol for 10 years now:
both clients and compositors implement this protocol to handle buffer
sharing. Compositors either use EGL_EXT_image_dma_buf_import or the
Vulkan dmabuf extensions to import these into GPU world.

We've had dmabuf since Linux kernel 3.4, so there's no need to carry
around this extension which encourages users to do bad things - namely,
to expose their buffers with a global ID that anyone can access - and
requires us to carry around some irritating support code.

The same could be said for Reset Notification Strategy and Robust Buffer
Access as implementations seem to be explicitely allowed to not succeed.
The EGL 1.5 spec says:
> "An EGL_BAD_MATCH error is generated if an OpenGL or OpenGL ES
> context is requested with robust buffer access and with a

> does not support that behavior."

As we do return these errors accordingly during context creation, stop
requiring drivers to implement successfull creation of robust contexts,
as indicated by the extension.

9bdab38424 egl: Implement EGL_MESA_x11_native_visual_id
EGL 1.5 specification requires to not match on EGL_NATIVE_VISUAL_ID.

EGL_MESA_x11_native_visual_id extension allows us to remove this
restriction for X11, where we need to match EGL_NATIVE_VISUAL_ID to find
visuals which allow blending.

The reasoning is that on X11, compositors use the visual as "magic bit"
to decide whether to alpha-blend surface contents.
Unlike on most (all?) other windowing systems, requesting an alpha channel
for the config alone does not already imply blending on the compositor
level.

Thus, in order to allow clients to explicitly request configs with
"magic bit" and, similar to GLX, to order configs in a way so clients
not requesting alpha-blending do not get it by accident, do match
visual ids.

Note that one consequence of this is that more configs get
reported to clients.

3825e24085 loader: silence implicit-load zink error by the loader
Since commit 7d9ea77b45 ("glx: add automatic zink fallback loading between hw
and sw drivers"), zink could be tried as a fallback. It'd better silence
if the zink loading is implicit and on fail as what commit 4cc975c6e9 ("glx: silence
more implicit-load zink errors") has done. But there seems to be one
left bebind, which is spit when building swrast but no zink with -Dglx=dri.

v2: plumb the flag through from egl/glx to the loader (zmike)

1ac1c0843f treewide: Replace usage of macro DEBUG with MESA_DEBUG when possible
This is achieved by the following steps:

#ifndef DEBUG => #if !MESA_DEBUG
defined(DEBUG) => MESA_DEBUG
#ifdef DEBUG => #if MESA_DEBUG

This is done by replace in vscode

excludes
docs,*.rs,addrlib,src/imgui,*.sh,src/intel/vulkan/grl/gpu

These are safe because those files should keep DEBUG macro is already excluded;
and not directly replace DEBUG, as we have some symbols around it.

Use debug or NDEBUG instead of DEBUG in comments when proper

This for reduce the usage of DEBUG,
so it's easier migrating to MESA_DEBUG

These are found when migrating DEBUG to MESA_DEBUG,
these are all comment update, so it's safe

Replace comment /* DEBUG */ and /* !DEBUG */ with proper /* MESA_DEBUG */ or /* !MESA_DEBUG */ manually

DEBUG || !NDEBUG -> MESA_DEBUG || !NDEBUG
!DEBUG && NDEBUG -> !(MESA_DEBUG || !NDEBUG)

Replace the DEBUG present in comment with proper new MESA_DEBUG manually

a3418105b9 egl/wayland: Remove EGL_WL_create_wayland_buffer_from_image
This extension was originally intended to complement
EGL_WL_bind_wayland_display.

The idea behind bind_wayland_display was that libEGL.so on the server
side could register Wayland extensions for libEGL.so on the client side
to use to create buffers, with eglQueryWaylandBufferWL being used to
query the buffer properties, and EGL_WAYLAND_BUFFER_WL added as an
EGLImage target for texturing.

eglCreateWaylandBufferFromImageWL was then to be used for nested
compositors to perform passthrough: it would take an EGLImage created by
the magical libEGL secret handshake, and make it usable in the parent
compositor by doing the same secret handshake again.

Since that original idea, we've just standardised dmabuf across the
Wayland ecosystem instead. The last known user of this extension was a
sample client in the Weston tree, which was broken quite some years ago
and never ported to the Meson build system when we moved.

Given it won't affect anyone, let's just remove this extension so no-one
thinks it would be a good idea to use it.

9cc3e842bb egl: Return BAD_CONFIG when robust access unsupported
EGL_EXT_create_context_robustness provides separate knobs for device
reset strategy and robust buffer access. As there is no separate query
for both piecies of functionality, devices which do not support robust
buffer access need to reject contexts created with that flag with
EGL_BAD_CONFIG.

Given that EGL can't do cap queries, we create a fake extension entry in
the EGLDisplay to cover whether the device can do robust buffer access
or just device-reset queries.

d913927fe9 egl/glx: fallback to software when Zink is forced and fails
When `MESA_LOADER_DRIVER_OVERRIDE` is set to `zink` and the display
initialization fails, fallback to software rendering.

The error was reported in #10123 and it can be reproduced with:

    $ MESA_LOADER_DRIVER_OVERRIDE=zink eglinfo

`eglinfo` would crash in `dri2_display_release()` because of
`assert(dri2_dpy->ref_count > 0)`.

After bisecting the error to commit 8cd44b8843 ("egl/glx: add
autoloading for zink"), I found out that, before this change, the
display was set to initialized even when `_eglDriver.Initialize(disp)`
failed:

    disp->Options.Zink = env && !strcmp(env, "zink");
    // disp->Options.Zink is true

    if (!_eglDriver.Initialize(disp)) {
       [...]
       // Zink initialization has failed at this point
       // However, success is set to true:
       bool success = disp->Options.Zink;
       if (!disp->Options.Zink && !getenv("GALLIUM_DRIVER")) {
          [...]
       }
       // Software initialization is ignored because success is true
       if (!success) {
          [...]
       }
    }

    // The display is set as initialized even though it shouldn't
    disp->Initialized = EGL_TRUE;

0fa85b983f mesa/st, dri2, wgl, glx: Restore flush_objects interop backward compat
In commit 1396dc1c a new output field was added as a parameter, but this
is a problem since the signature of the function are not versionned.

The flush function didn't have a versionned output struct. So what I'm
proposing here is that if the version of the input argument is new enough
(bumped to 2 here), then we re-use the existing argument, which until now
was directly a pointer to GLsync, and instead use it as a pointer to a
versioned struct.

We're just changing one pointer type to another, so in C, this should
be fine AFAIK.
