Use caps to obtain the multisample sample positions for up to 16
positions and implement the according Gallium interface.
This implemenation (plus its counterpart in virglrenderer) assume that
the fixed sample position are always the same for a given number of samples
over the whole live time of a qemu session. It also assumes that sample
series are only given for 2, 4, 8, and 16 samples, and for intermediate
numbers N of samples the next higher supported set from above list is picked
and the sample positions for the first N samples are returned accordingly.
Fixes (when run on GL host):
dEQP-GLES31.functional.texture.multisample.samples_1.sample_position
dEQP-GLES31.functional.texture.multisample.samples_2.sample_position
dEQP-GLES31.functional.texture.multisample.samples_3.sample_position
dEQP-GLES31.functional.texture.multisample.samples_4.sample_position
dEQP-GLES31.functional.texture.multisample.samples_8.sample_position
dEQP-GLES31.functional.texture.multisample.samples_10.sample_position
dEQP-GLES31.functional.texture.multisample.samples_12.sample_position
dEQP-GLES31.functional.texture.multisample.samples_13.sample_position
dEQP-GLES31.functional.texture.multisample.samples_16.sample_position
v2: remove unrelated chunk (thanks Ilia Mirkin)
v3: - also return positions for intermediate sample counts
- fix unused varible warning
- update description
v4: explain better what this patch assumes and how it handles sample numbers
that are not directly advertised (thanks go to Erik Faye-Lund for making
me aware that this should be documented)

Build & install
---------------
You can find more information in our documentation (`docs/install.html
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.html <https://mesa3d.org/meson.html>`_):
.. 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.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.
The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_
