Right, this was more of a cleanup for the server's benefit so that
pulling in the proto headers wouldn't drag in datatypes from the
client side. But both the client and server are always going to need
pull in the protocol headers such as <X11/X.h>. The only way to avoid
that would be to duplicate them into the server and all the libraries.
