Adam Jackson 988762679c meson: Add "amber" option for automatic LTS build configuration
Setting amber to true changes these defaults:

- glvnd defaults to enabled
- the glvnd vendor name is set to "amber"
- the gallium and vulkan drivers are disabled
- prefer-iris defaults to false
- eglQueryString(EGL_VENDOR) returns "Mesa Project (Amber)"

The megadriver for the classic driver set will be installed to a file
name unique from Mesa main. Beyond that no attempt is made to use
filenames different from main - particularly not if glvnd is explicitly
disabled - so you would still need to configure your install paths
appropriately so things don't collide, if you want them to not collide.
But if you have that problem, consider that glvnd already solves it.

This has a quiet dependency on glapi and gbm's library API remaining
stable. gbm you could fix by linking it statically, glapi is a little
harder. I think the right move for glapi is to use glvnd's gldispatch
more directly, but that's not public API at the moment.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library
======================================================


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://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <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 `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.
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>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
(`docs/bugs.rst <https://mesa3d.org/bugs.html>`_).


Contributing
------------

Contributions are welcome, and step-by-step instructions can be found in our
