IIRC, not all headers were fixed by Peter's work. So, unless we decide 
to let them be, there's still a risk of header movement.

Please no, that won't help at all. The current split protos are fine 
from a packaging PoV. It's what's inside each header that can cause 
problems.

However, if we really want to avoid this mess again, we should 
definitely get server-side xcb done sooner than later. This way, the 
server would be fully independent of the old libs and protos.

If xcb is to be the future of X library-wise, we should definitely make 
it a priority for the server.

libdrm isn't too much of a problem distribution-wise since only the 
server and mesa use it. And since we tend to keep mesa and the server in 
sync, adding libdrm to the list isn't that much more work.
