Since we're now using xcb for upstream X11 connection, it's cleaner to
use it's type for the window IDs.

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.

Instead of going through mi machinery, just pass the ClearArea
request to the upstream window.

For cleaner code, make sure every source needing something from Xdefs.h
does explicitly include it (not relying on indirect including)

A careful read shows that it was always NULL. It hasn't always been; as
the DDX spec indicates, it was the "occluded region that has backing
store", but since that backing store code is long gone, we can nuke it.
mi{,Overlay}WindowExposures get slightly simpler here, and will get even
simpler in just a moment.

This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:
-bap
-psl
-T PrivatePtr
-T pmWait
-T _XFUNCPROTOBEGIN
-T _XFUNCPROTOEND
-T _X_EXPORT
The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:
dir1=$1
dir2=$2
for dir in $dir1 $dir2; do
(cd $dir && find . -name '*.o' | while read file; do
dir=`dirname $file`
base=`basename $file .o`
dump=$dir/$base.dump
objdump -d $file > $dump
done)
done
find $dir1 -name '*.dump' | while read dump; do
otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
diff -u $dump $otherdump
done

This patch only changes the API, not the implementation of the
devPrivates infrastructure. This will permit a new devPrivates
implementation to be layed into the server without requiring
simultaneous changes in every devPrivates user.

Propagate the shape kind all the way to SetShape to avoid performing non-input
operations such as revalidating the tree and generating exposures when only
changing a window's input shape.

This was an attempt to avoid scratch gc creation and validation for paintwin
because that was expensive. This is not the case in current servers, and the
danger of failure to implement it correctly (as seen in all previous
implementations) is high enough to justify removing it. No performance
difference detected with x11perf -create -move -resize -circulate on Xvfb.
Leave the screen hooks for PaintWindow* in for now to avoid ABI change.

Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.

(https://bugs.freedesktop.org/attachment.cgi?id=2005): Fix Xnest to
update the shape regions in the backend server whenever a client
changes them in Xnest (the fix is to add a new wrapper which calls
|xnestShapeWindow()| before calling |miSetShape()|). Patch by Mark
