Change winIconIsOverride() to take a HICON parameter, so some unneccessary

The formatter confused address operators preceded by casts with
bitwise-and expressions, placing spaces on either side of both.
That syntax isn't used by ordinary address operators, however,
so fix them for consistency.

winOverrideIcon() is called from the internal WM client thread.
Accessing server-internal data structures to get icon data or window hints is
not safe, as there is no lock to ensure we do not collide with these data
structures being updated in the server thread.
Rewrite so the internal client thread uses X client calls to obtain this data
safely
We used to also set the icon inside the server when the window was initially
created. For simplicity, we simply send a message to the internal WM to update
the icon when the window is created (rather than writing different icon update
code which can work in the server thread for that one case...)
extwm mode used to do the icon update in the server. I'm not sure that actually
made much sense. Let's assume the external WM client can do it instead...
v2
Make sure that WM_WM_ICON_EVENT does nothing for override-redirect windows
v3
Reinstate check that native window actually has expected properties for an X
window before trying to update it's icon; some auxiliary windows owned by the
XWin process don't, which would cause a crash
v4
Various fixes to pixmap icon conversion:
- remove left-over malloc in winScaleXimageToWindowsIcon causing a memory leak
- don't recalculate DDBitmap stride in winScaleXimageToWindowsIcon, when we already have worked it out
- properly check that XGetWindowProperty(NET_WM_ICON) returned some data
- don't try to retrieve WM_HINTS icon_mask if it isn't set
- restore accidentally dropped calculation of effBpp, stride, maskStride of output DDBitmap
- make sure imageMask is zero-initalized before we use it to mask the DDBitmap
v5
Remove a left-over unused variable
v6
Avoid XDestroyImage(NULL) crash if XGetImage failed for icon_pixmap

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

For the global variables defined in winglobals.c, remove duplicate extern
declarations from the beginning of various .c files, and move most of them
into a new header file, winglobals.h
Leave some clipboard related variables alone for the moment, they need treating
more carefully, to avoid mixing client and server type definitions.
