X.Org integration

[Eric Anholt]

Well, the modularization isn't going as fast as I had hoped, so what I'm
working on is to just make a new xorg-libraries monolithic port of
6.7.0, and probably xorg-clients as well.  I'll change xorg-server to
depend on xorg-libraries unless some WITH_MODULAR switch is set, and
leave the modular libs around (with an informative IGNORE if the switch
isn't set) because those ports should be useful some day soon.  I'll
work on the other monolithic ports as much as I can, but I feel like the
others (manpages, print/nest/font/vfbserver, fonts) either don't get
used as much or don't require being up to date as seriously as libs,
clients, and server do.  I want to do them soon, but real life is
getting in the way.

I'm not sure how to deal with the versioning if we want to support both
XFree86-libraries and xorg-libraries (I don't want to, and would love to
see XFree86-libraries disappear when xorg-libraries comes around).  Are
there any concrete arguments to keep XFree86-libraries around if
xorg-libraries suits our needs?  Note that we'll be installing more
shared libraries with xorg-libraries than the old XFree86-libraries port
does, so swapping them in and out won't really work.

As far as BC issues that came up on IRC recently, here's the deal. 
Everything in XFree86-libraries should be backwards compatible with
XFree86 stuff.  The one BC issue in X.Org that's known is that the X.Org
server only speaks the new xinerama protocol and not the old one, so
it'll work with an X.Org libXinerama but not an XFree86 one.  But the
X.Org libXinerama should support the XFree86 server fine.
