Xnest: use XCB for upstream connection
...
Now that no Xlib operations (besides opening and closing connection)
aren't used anymore, we can move over the last pieces and use XCB
instead of Xlib for connecting the upstream Xserver.

Xnest: use XCB for event loop
...
Now that no X11 calls are being done via Xlib anymore, we're free to
also move over event receiving, leaving Xlib pretty much unused.
Also need to add a simple event queue mechanism, because we've go a
screen operation (see xnestBitBlitHelper) that needs to collect up
certain events for it's return value.

Xnest: drop xnestWindowExposures micro-optimization
...
xnestWindowExposures() is a micro-optimization for the specific case that
a newly created window receives exposure events (from our upstream server)
inside the region we're already exposing on our own (miWindowExposures()):
it peeks the Xlib event queue for all expose events, checks whether their
areas are inside our exposure region and requeue's those that aren't.
Unfortunately, this depends on Xlib's internal queue mechamism, thus standing
in the way of moving to XCB (which doesn't have that).
Removing this doens't seem to make any practical difference, even with
demanding applications like GIMP. The only cost is potentially having some
initial window content painted twice, *if* the application really draws
something complicated right after creating the window.
*If* there'll really be a demand for such an optimization some day, it can
be reimplemented without any message queue: just redirecting all expose events
into recording them in a region, which is flushed out later. But for now,
there really doesn't seem to be any practical need for that.
