6d9ca1d4e4 util/meson: include inc_gallium
There are several dependencies on headers from
   /gallium/include/pipe/

which currently mean that dependencies on util
must include gallium to compile.

bdd460fdcb util: Add an implementation of qsort_r for non-GNU platforms
Android and MSVC don't have qsort_r() so let's provide a util wrapper
that uses the old qsort and thread-local storage.  We use C++ for this
because thread_local is built into C++11 and we can't rely on C11
everywhere.

eca6bb9540 util/fossilize_db: add basic fossilize db util to read/write shader caches
My benchmarking shows no significant change in cache load times with a
single shader cache file vs the existing cache implementation of many
small files (tested with my spinning rust HDD).

However this new single file cache implementation does reduce the total
size on disk used by the shader cache. We have a problem with the existing
cache where writing tiny files to disk causes more disk space to be used than
is actually needed for the files due to the minimum size required for a file.
In pratice this tends to inflate the size of the cache on disk to over 3x
larger.

There are other advantages of using a single file for shader cache entries
such as allowing better removal of cache entries once we hit the max cache
size limit (although we don't implement any max cache size handling in this
initial implementation).

The primary reason for implementing a single file cache for now is to allow
better performance and handling by third party applications such as steam
that collect and distribute precompiled cache entries.

For this reason we also implement a new environment variable
MESA_DISK_CACHE_READ_ONLY_FOZ_DBS which allows a user to pass in a path
to a number of external read only shader cache dbs. There is an initial
limit of 8 dbs that can be passed to mesa like so:

MESA_DISK_CACHE_READ_ONLY_FOZ_DBS=/full_path/filename1, ... ,/full_path/filename8

Where the filename represents the cache db and its index file e.g.
filename1.foz and filename1_idx.foz

2fb2749937 android: Disable the user XML config parsing.
The android platform is not interested in this feature of Mesa.  There are
currently workarounds for apps on Android, and no support for it in the
xmlconfig code.  Even if there we do need workarounds eventually, we'll
want to bake them in as structs rather than have this awkward external
dependency for parsing user-readable data installed by Mesa for
Mesa-internal details.

This gets rid of the expat dependency in the turnip driver.

Note that rather than have more #ifdefs in the file, I've opted to move
the code to have more logical locations since the structs refactor had
left less-used helpers scattered across the file.

We can generate the XML if anybody actually queries it, but this reduces
the amount of work in driver setup and means that we'll be able to support
driconf option queries on Android without libexpat.

This updates the driconf interface struct version for i965, i915, and
radeon to use the new getXml entrypoint to call the on-demand xml
generation.  Note that our loaders (egl, glx) implement the v2 function
interface and don't use .xml when that's set, and the X server doesn't use
this interface at all.

13ea7db760 mesa: Promote Intel's simple logging façade for Android to util/
I'm bringing up freedreno Vulkan on an Android phone, and my pains are
exactly what Chad said when working on Intel's vulkan for Android in
aa716db0f6 ("intel: Add simple logging façade for Android (v2)"):

    On Android, stdio goes to /dev/null. On Android, remote gdb is even
    more painful than the usual remote gdb. On Android, nothing works like
    you expect and debugging is hell. I need logging.

    This patch introduces a small, simple logging API that can easily wrap
    Android's API. On non-Android platforms, this logger does nothing
    fancy.  It follows the time-honored Unix tradition of spewing
    everything to stderr with minimal fuss.

    My goal here is not perfection. My goal is to make a minimal, clean API,
    that people hate merely a little instead of a lot, and that's good
    enough to let me bring up Android Vulkan.  And it needs to be fast,
    which means it must be small. No one wants to their game to miss frames
    while aiming a flaming bow into the jaws of an angry robot t-rex, and
    thus become t-rex breakfast, because some fool had too much fun desiging
    a bloated, ideal logging API.

Compared to trusty fprintf, _mesa_log[ewi]() is actually usable on
Android.  Compared to os_log_message(), this has different error levels
and supports format arguments.

The only code change in the move is wrapping flockfile/funlockfile in
!DETECT_OS_WINDOWS, since mingw32 doesn't have it.  Windows likely wants
different logging code, anyway.

b6fd679a9e mesa/main/util: moving gallium u_mm to util, remove main/mm
Right now there are two copies of mm:
   * mesa/main/mm.[ch]
   * gallium/auxiliary/util/u_mm.[ch]

At some point they splitted, and from the commit message it was not
clear why it was not possible to have only one copy at a common place.

Taking into account that was several years ago, Im assuming that it
was not possible then.

This change would allow to have one copy of the same code, and also
being able to use that code out of mesa/main or gallium, if needed.

This commit moves u_mm and removes mm, as u_mm has slightly more
changes.

882ca6dfb0 util: Move gallium's PIPE_FORMAT utils to /util/format/
To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to
move their helpers out of gallium.  Since u_format used
util_copy_rect(), I moved that in there, too.

I've put it in a separate directory in util/ because it's a big chunk
of related code, and it's not clear to me whether we might want it as
a separate library from libmesa_util at some point.

Closes: #1905
