Add a new MESA_LOG_PREFIX environment variable that allows fine-grained
control over log prefixes in file logger output on Linux. The variable
accepts a comma-separated list of options:
- "tag": include the tag prefix (e.g., "MESA:")
- "level": include the level prefix (e.g., "info:")
By default, both tag and level are included. Users can customize the
prefix by setting MESA_LOG_PREFIX to any combination (e.g., "tag",
"level", "tag,level", or empty string for no prefix), making the output
more flexible and readable for different use cases.
Other loggers (syslog, Android logcat, Windows debugger) are unaffected
and continue to include tag and level information as appropriate for
their format.

Setting MESA_VK_VALIDATE_SHADER_BINARIES will cause the shader code to
round-trip every shader through [de]serialize and only ever use the
deserialized version. This catches bugs where the driver may drop
things in the [de]serialization process. It also deserializes the new
shader again and compares it against the original to ensure that
deserialize -> serialize is idempotent.

NIR+ACO is the best SSA-based shader compiler for AMD GPUs that exists.
There are many reasons why NIR+ACO is better than LLVM, and I have a long
list that I've collected over the years, but the major ones are better GPU
performance (faster GPU memory access thanks to better clauses and
scheduling, a lot less SGPR/VGPR spilling, better loop support, slightly
smaller shader binaries), 8x lower shader compile times, and smaller memory
footprint of the IR.
It also shows that NIR is a mature SSA-based shader compiler that helps
drivers generate optimized code very quickly.
And most importantly, radeonsi has slightly better Viewperf performance
with NIR+ACO than LLVM, and that's difficult to ignore.

Add documentation describing Android system property usage in Mesa. For
example, how environment varible names are translated by
os_get_option(), how to get/set values, and corresponding example
commands.
A new section is added to doc/envvars.rst which points to the full
details within the new "Android System Properties" section in
docs/android.rst.

vkd3d-proton (DX12) and Zink (GL) have always been enabling features
that require the global BO list to be enabled.
Since DXVK 2.7+ (August 2025), it's also always enabled by default for
DX9-11 games (because it requires BDA now).
The global BO list used to decrease performance in the past mostly
because of bad memory management in AMDGPU, but it seems the situation
slightly improved since. Though, there might still some workloads that
hit the issue, but I think it should be mostly good overall.
This introduces RADV_DEBUG=nobolist to disable the global BO list
when no features require it.

Instead of dumping multiple files with the optimizer passes, write a single
archive file with all the contents. The actual file is created
by the drivers, so later commits will actually enable the feature in
anv and iris.
This removes the use of INTEL_DEBUG=optimizer (and the corresponding
enum value) in brw. That environment variable is still used by ELK --
which currently doesn't support mda.

The full HiZ workaround is the only one that fixes the issue reliably.
Sadly, the performance results are mixed and sometimes it hurts. To
maintain performance, RADV will opt-in by selecting which workarounds
to apply from drirc.
As we can't know the full list of games that will be affected by a
potential performance regression, users are encouraged to try with
RADV_GFX12_HIZ_WA (see Mesa documentation for more explanations).

The option creates a buffer where each bit stores whether the
corresponding 4096 byte memory section has been allocated. The helper
radv_build_is_valid_va allows for querying the validity of addresses
inside a nir shader which can be useful for debugging.

Over past months a performance issue was found with the Mesa-DB cache
implementation that results in a too slow cache startup time when cache is
full. A better indexing strategy will need to be invented to mitigate the
issue. Until then, let's default back to the multi-file cache.
