docs: update trademark disclaimer

It's a *long* time since SGI was the copyright holder for the OpenGL
trademark. And we implement more APIs by now, so let's update the
disclaimer to instead redirect to the Khronos licensing page for
details.

While we're at it, soften the language on legal status as a formal
implementation, as we currently have conformant drivers for most of the
APIs by now. But refer to the Khronos website for details, as
conformance status for drivers are subject to change.

intel/compiler: Implement Mesh Output

Because we keep around the non-arrayed offset AND the pitch is

intel/compiler: Implement Task Output and Mesh Input

Implement the output written by the task *workgroup* and available to

ignore any layout annotations (since they are not really testable) and

The URB messages are only SIMD8, so for larger SIMDs, the functions

the generic lower_simd_width() since it is not just a matter of
zip/unzip, e.g. the offset must be adjusted.

Indirect writes/reads are implemented by handling one component at a

mesa: Merge libmesa_gallium and libmesa_common

Since we don't have libmesa_classic anymore, we don't nee to split
these, and can save a target/ar invocation by not having two targets.
Plus it's just conceptually simpler

From the GL_OES_texture_buffer spec:

      "If no buffer object is bound to the buffer texture, the results

this can be interpreted as allowing any result to come back, but not

The current solution is not entirely complete, as it could still try to

This can be checked with piglit test
