Based on Vladislav Egorovs work on the preprocessor, but split
out to a util functionality that should be universal. Setup, teardown,
memory handling and general layout is modeled around the hash_table
and the set, to make it familiar for everyone.
A notable change is that this implementation is always null terminated.
The rationale is that it will be less error-prone, as one might
access the buffer directly, thereby reading a non-terminated string.
Also, vsnprintf and friends prints the null-terminator.

On some platforms, gcc generates library calls when __atomic_* functions
are used, but does not link the required library (libatomic) automatically
(supposedly to allow the app to use some other atomics implementation?).
Detect this at configure time and add the library when needed. Tested
on armel (library was added) and on x86_64 (was not, as expected).

This option enables a performance optimization where typical non-blending
draws with depth buffer may be rasterized out-of-order (on VI+, multi-SE

This optimization can lead to incorrect results when an applications

Fix the build for Android Nougat.
The dladdr(3) manpage says that <dlfcn.h> is required. On Linux, the
build succeeded without it because build_id.c includes <link.h> which
includes <dlfcn.h>. On Android, we must include <dlfcn.h> directly.

Reviewed-by: Matt Turner <mattst88@gmail.com>
This patch renames build_id_find_nhdr() to
build_id_find_nhdr_for_addr(), and changes it to never examine the
library name.
Tested on Fedora by confirming that build_id_get_data() returns the same
build-id as the file(1) tool. For BSD, I confirmed that the API used
(dladdr() and struct Dl_info) is documented in FreeBSD's manpages.
This solves two problems:
- We can now the query the build-id without knowing the installed library's
filename.
This matters because Android requires specific filenames for HAL
modules, such as "/vendor/lib/hw/vulkan.${board}.so". The HAL
filenames do not follow the Unix convention of "libfoo.so". In
other words, the same query code will now work on Linux and Android.
- Querying the build-id now works correctly when the process
contains multiple shared objects with the same basename.
(Admittedly, this is a highly unlikely scenario).

Steam is already analysing cache items, unfortunatly we did not

Since we are renaming it we take the opportunity to give the directory

Adding a version field to the header of cache entries will help us to
avoid having to rename the directory in future. Please note this is
versioning for the internal structure of the entries as defined in
disk_cache.{c,h} as opposed to the structure of the data provided to
the disk cache by the GLSL compiler and the various driver backends.

VC4 has had a tension, similar to pre-Sandybridge Intel, where we want to
use low-numbered registers (more parallelism on Intel, fewer delay slots
on vc4), but in order to give instruction scheduling the most freedom to
avoid delays we want to round-robin between registers of the same cost.
Our two heuristics so far have chosen one end or the other of that
tradeoff.
The callback, instead, hands the driver the set of registers that are
available, and the driver gets to make its own choice. This will be used
in vc4 to round-robin between registers of the same cost, and might be
used in the future for improving bank selection.

The previous implementation of CLAMP() allowed NaN to pass through
unscathed, by failing both comparisons. NaN isn't exactly a value
between MIN and MAX, which can break the assumptions of many callers.
This patch changes CLAMP to convert NaN to MIN, arbitrarily. Callers
that need NaN to be handled in a specific manner should probably open
code something, or use a macro specifically designed to do that.
Section 2.3.4.1 of the OpenGL 4.5 spec says:
"Any representable floating-point value is legal as input to a GL
command that requires floating-point data. The result of providing a
value that is not a floating-point number to such a command is
unspecified, but must not lead to GL interruption or termination.
In IEEE arithmetic, for example, providing a negative zero or a
denormalized number to a GL command yields predictable results,
while providing a NaN or an infinity yields unspecified results."
While CLAMP may apply to more than just GL inputs, it seems reasonable
to follow those rules, and allow MIN as an "unspecified result".
This prevents assertion failures in i965 when running the games
"XCOM: Enemy Unknown" and "XCOM: Enemy Within", which call
glTexEnv(GL_TEXTURE_FILTER_CONTROL_EXT, GL_TEXTURE_LOD_BIAS_EXT,
-nan(0x7ffff3));
presumably unintentionally. i965 clamps the LOD bias to be in range,
and asserts that it's in the proper range when converting to fixed
point. NaN is not, so it crashed. We'd like to at least avoid that.

If the job which is currently being executed tries to lock the mutex,
it will be stuck forever, because util_queue_add_job is stuck.
The deadlock can be trivially resolved by increasing the queue size

Then util_queue_add_job becomes wait-free.
