Timothy Arceri 644fcd9486 util/disk_cache: make use of single file cache when env var set
When the MESA_DISK_CACHE_SINGLE_FILE environment variable is set
we make use of the new single file shader cache implementation.

The new cache uses the following directory structure based on the
first defined name as follows:

 $MESA_GLSL_CACHE_DIR/driver_id/gpu_name/foz_cache.foz
 $MESA_GLSL_CACHE_DIR/driver_id/gpu_name/foz_cache_idx.foz

 $XDG_CACHE_HOME/mesa_shader_cache_sf/driver_id/gpu_name/foz_cache.foz
 $XDG_CACHE_HOME/mesa_shader_cache_sf/driver_id/gpu_name/foz_cache_idx.foz

 <pwd.pw_dir>/.cache/mesa_shader_cache_sf/driver_id/gpu_name/foz_cache.foz
 <pwd.pw_dir>/.cache/mesa_shader_cache_sf/driver_id/gpu_name/foz_cache_idx.foz

Where foz_cache_idx.foz is a database of offsets pointing to the location of
the shader cache entries in foz_cache.foz

This initial implementation doesn't have any max cache size handling and is
initially intended to be use by applications such as steam that will handle
cache management for us.

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
