Enrico Weigelt, metux IT consult fb38ed0917 composite: clean up including panoramix headers
* use their actual path instead of relying this to be in compiler's
  include path list.
* no need to do it only conditionally, no #ifdef needed

Enrico Weigelt, metux IT consult c6b8b78a29 composite: use calloc() instead of malloc()
Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.

The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.

The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

Enrico Weigelt, metux IT consult fb696a7d7b rename old symbol PANORAMIX to XINERAMA
PANORAMIX was the original working title of the extension, before it became
official standard. Just nobody cared about fixing the symbols to the official
naming.

For backwards compatibility with drivers, the old PANORAMIX symbol will
still be set.

Enrico Weigelt, metux IT consult a917f6a8a8 drop obsolete HAVE_DIX_CONFIG_H
The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.

This commit only removes them from our own source files, where we can
guarantee that dix-config.h is present - leaving the (potentially exported)
headers untouched.

Enrico Weigelt, metux IT consult 85d4bd0dba rename remaining RT_* defines to X11_RESTYPE_*
Since we already had to rename some of them, in order to fix name clashes
on win32, it's now time to rename all the remaining ones.

The old ones are still present as define's to the new ones, just for
backwards compatibility.

Enrico Weigelt, metux IT consult 232cad9ec3 prevent name clash on Windows w/ RT_* defines
Windows' native headers using some our RT_* define's names for other things.
Since the naming isn't very nice anyways, introducing some new ones
(X11_RESTYPE_NONE, X11_RESTYPE_FONT, X11_RESTYPE_CURSOR) and define the old
ones as an alias to them, in case some out-of-tree code still uses them.

With thins change, we don't need to be so extremely careful about include
ordering and have explicit #undef's in order to prevent name clashes on
Win32 targets.

Keith Packard 60014a4a98 Replace 'pointer' type with 'void *'
This lets us stop using the 'pointer' typedef in Xdefs.h as 'pointer'
is used throughout the X server for other things, and having duplicate
names generates compiler warnings.

Adam Jackson 1dd839a425 composite: Fix COW creation for Xinerama (v2)
Say you have two 800x600 screens left/right of each other.  A window
that's 200x200 at +700+0 in protocol coordinate space will appear to be
at -100+0 in the coordinate space of the right hand screen.  Put another
way: windows are in the coordinate space of their root window pixmap.

We weren't doing this translation for the COW, so when rendering came in
to it you'd see the top-left chunk of the COW on all screens.  Cool
effect and all, but wrong.

v2: Only translate when Xinerama is active [keithp]

Keith Packard 9838b7032e Introduce a consistent coding style
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

Jamey Sharp e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.
Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix uses this data, a screen private entry isn't appropriate.

xf86-video-dummy currently uses WindowTable, so it needs to be updated
to reflect this change.

Mikhail Gusarov 3f3ff971ec Replace X-allocation functions with their C89 counterparts
The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.

X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.

Havoc Pennington 1731882341 Set bg pixmap of composite overlay window to None (#20912)
Otherwise it's impossible to get the COW without a white
flash on the screen, because it's on top, mapped immediately,
and unaffected by composite redirection. This makes
initial login ugly when it doesn't need to be.

Keith Packard efa65a0317 Rework composite overlay window code to fix several resource management bugs.
The composite overlay window code had several misunderstandings of the
workings of the X server, in particular error handling paths would often
double-free objects. Clean all of this up by using resource destruction as
the sole mechanism for freeing resource-based objects.
