XFree86 Design doc: Explain this version covers the current Xorg release 

Update the title & preface to explain that while this was originally
the XFree86 4.0 design, we've changed a lot since forking.

The broad design principles are:
This document was originally the design spec for the DDX layer of the
XFree86 4.0 X server. The X.Org Foundation adopted the XFree86 4.4rc2
version of that server as the basis of the Xorg server project, and has
evolved the XFree86 DDX layer greatly since forking. This document thus
covers only the current implementation of the XFree86 DDX as found in the
Xorg server &xserver.version; release, and no longer matches the XFree86
server itself.

Unless we find major deficiencies in the DIX layer, we should avoid
making changes there.
While the XFree86 project had a goal of avoiding changes to the DIX
layer unless they found major deficiencies there, to avoid divergence from
the X.Org sample implementation they were integrating changes from, the
X.Org developers now maintain both sides, and make changes where they are
most appropriate. This document concentrates on the XFree86 DDX layer used
in the Xorg server itself (the code found in <filename>hw/xfree86</filename>
in the source tree), and developers will also want to refer to the
<filename>Xserver-spec</filename> documentation that covers the DIX layer
routines common to all the X servers in the sample implementation.
