Arch Linux

Starting from [pychess 0.99.3-1](https://git.archlinux.org/svntogit/community.git/commit/trunk?h=packages/pychess&id=0dd26069a8d479af24d9a7244e3cf1ecd360ff15), pychess conflicts with mesa-demos. Looking at the files provided by pychess, and the ones provided by mesa-demos, there's really no overlap.

At a glance, the conflict doesn't appear evident. And AFAIK, mesa-demos is the only provider of `glxinfo`, which is an application I'd rather have always available.

I don't need clingo, but that was as well added as a conflicting package, besides mesa-demos, and again, at a glance, that doesn't seem necessary.

Can the mesa-demos conflict be removed, so that pychess and mesa-demos can coexist? Not sure if possible, and for sure I don't need it at all, but could the clingo conflict be removed as well?

Thanks !
