Migrating to unified xorgproto usage

the best of my understanding is that all of the proto packages except xcbproto have been superseded by xorg-xorgproto, which basically bundles all of them up. It would be nice to migrate to the new bundled package, but I think it would require a fairly aggressive migration since it has file conflicts with all of the other proto packages. The protocol files barely ever change so I don't think the conflicts would actually cause problems, but it would leave to some pretty long sets of warnings when installing both kinds.

I believe that we can build a migrator and a piggy back migrator to move everything to the new organization.

I mostly wanted to leave this here to keep track of the originally suggested idea.

It is worth mentioning that although it is rare, new protocol definitions are sometimes introduced in the xorgproto library, and the newest versions of some of the X.org libraries will not build without them. So, in order to be able to stay fully up-to-date with the X.org releases, we will need to do this migration.
