Enrico Weigelt, metux IT consult c90974c00d xnest: add pixmap depths to global depth list
Right now, we're only registering the depths of our visuals, which are
mirroring upstream's visuals. But forgotten to register the pixmap depths
that don't have an assiocated visual.

Enrico Weigelt, metux IT consult 3c028a8cc0 miext: move over extinit_priv.h from include
Since most of the extension init logic (and on/off switches for them)
is driven from miext, this seems the appropriate place for the header.

Enrico Weigelt, metux IT consult 5038b4e413 Xnest: use xcb_window_t instead of Window
Since we're now using xcb for upstream X11 connection, it's cleaner to
use it's type for the window IDs.

Now that we completely ported from Xlib to XCB, we can finally stop

Enrico Weigelt, metux IT consult 9969258e44 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.

Enrico Weigelt, metux IT consult 4716ee9981 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.

Enrico Weigelt, metux IT consult 8c701832ea 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.

This is a temporary measure, until xcbproto / libxcb is fixed:

Once xcbproto/libxcb is fixed (and new xcb release is out), this
commit can be reverted.
