mesa3d-headers is a little bit special: it uses the same sources as
the mesa3d package, named just 'mesa' upstream. mesa uses the meson
buildsystem, an that is what we use in the mesa3d package.
However, mesa3d-headers does not install the whole of mesa; it only
installs a select set of headers for those binary blobs that do not
provide them.
mesa does not provide such a feature (only installing headers) with
its meson buildsystem. As a consequence, we've made mesa3d-headers a
generic package, that basically only copies headers over.
Additionally, mesa3d-headers also provides the dri.pc file for when
Xorg is enabled; see 7468b60e7c (package/mesa3d-headers: also install
dri header and .pc file).
We used to manually generate that file from a .in template that was
present in mesa source code at the time it was still using autotools.
But when they switched over to using meson, the template was dropped
[0], and the dri.pc is now entirely generated using meson internals
[1].
So we now have no template present in the source code, so we must
come up with our own. This simplifies the replacement pattern to
just inject the version string.
