Ian Forbes f219b9e14a svga: Increase max_combined_shader_output_resources and SSBO limit to 16
The gl43 capability indicates we have a DX11.1+ device which supports
64 UAVs shared across all stages. This limit is roughly equivalent to
GL_MAX_COMBINED_SHADER_OUTPUT_RESOURCES which is controlled by
caps.max_combined_shader_output_resources which we currently set to
SVGA_MAX_SHADER_BUFFERS (8) which is probably too low since this limit
is also supposed to include render targets which we also set to 8.

The shader linker will validate that the pipeline does not exceed this
combined limit so we don't have to worry about the sum of the max for all
stages (16*5=80) now exceeding it.

Increasing the combined limt and the number of SSBOs from 8 to 16 allows
Blender to run as it requires 12 SSBOs. In theory we could increase the
combined limit to 56 but these limits are poorly documented and
implemented.

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install

Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.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.
