Switch to xorgproto instead of individual packages

Upstream used to distribute protocol headers as separate packages, but has
decided to merge those to a common package, named xorgproto.  This update
tracks that change.

* Add a new port, x11/xorgproto, with are protocol headers for xorg.
* Hook the new protocol port to the build and to infrastructure in
  bsd.xorg.mk.
* Update all ports with a dependency on any of the old *proto packages to
  instead depend on xorgproto.  Bump portrevision.
* Delete the old *proto packages, update MOVED.
