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 013374b8c1 Xnest: add helper for retrieving GC XID on upstream connection
Upcoming patches will need to retieve GC's XIDs on the upstream connection.
Moving this out into separate .c file, in order to not creating more
dependencies on Xlib headers, which we wanna get rid of.

For now, looking at the Xlib GC structure, attached to our DDX GCs.
When all users of the Xlib GC have gone (ie. moved all consumers to xcb),
we'll create the GC via xcb directly, thus replacing the Xlib GC struct
by XID - the interface of this helper will remain the same.

Enrico Weigelt, metux IT consult 467ee9eba7 Xnest: fetch xcb setup data
Fetching the setup data from xcb instead of Xlib, storing in our own struct,
holding all information needed for one particular upstream connection.
For now, there's only one, but future multi-upstream implementation will
change this to an array (and storing pointers to particular upstream in
various places).
