The backtrace buffer size (BT_SIZE) is determined by compile time,
so we can change BT_SIZE into a #define to turn vla into fixed array.

No need to have duplicated byte swapping macros in GLX for things that
the core alreay provides. Using core's macros is actually even easier.

We now have two copies of the same write path in both swapped and
non-swapped branch. One is enough.

The reply length (in units as well as bytes) can safely be determined
at compile time, by using sizeof() operator. No need for unnecessarily
complicated shifting bits back and forth.

The spec defines the reply as array of "CARD32", not "int". The latter
just accidentially has the same type (for now :o), but it's *semantically*
incorrect. Using CARD32 instead.

Our array here really is fixed, but it's size is determined by a variable
(that's assigned a fix values), unncessarily making it a VLA (even making
it const doesn't change that), so giving false alarms when compiling w/
-Wvla or -Werror=vla.
Replacing the variable by #define trivially fixes this.

The reply struct's size can safely be determined by the sizeof()
operator, so no need for using an extra define here. Making the code
easier to read and also open the door for future convenience macros
that might determine the buffer size on their own.

Assigning structs at declaration is quicker to read/understand. No need
to support ancient compilers that couldn't do that, anymore.

Now that we completely ported from Xlib to XCB, we can finally stop
importing Xlib :)
FIN.

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.

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.

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.

Use the visuals lookup table introduced by previous commit for
looking up local vs upstream visuals and their colormaps.
Replacing the the old Xlib visuals table.

Record the associations between host's and our visuals as well their

This is a temporary measure, until xcbproto / libxcb is fixed:
keep an own copy of the fixed xcb_xkb_get_kbd_by_name(), renamed
as xcb_xkb_get_kbd_by_name_1().
Once xcbproto/libxcb is fixed (and new xcb release is out), this
commit can be reverted.
