Enrico Weigelt, metux IT consult f7fdaf814b (submit/rename-panoramix-sym) 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.

Enrico Weigelt, metux IT consult 31c8867db4 (submit/drop-obsolete-have-dix-config.h) 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 cdc18a6013 (!1614) xfixes: use stack allocation and static init for reply structs
Canonicalize all reply structures onto stack allocation and static
initialization, like already done in most other extension. So make
the code easier to understand and allow further simplifications by
subsequent commits. Also gaining a little bit efficiency by skipping
some heap allocations.

Dynamically sized buffers (where the upper bound isn't known), are
still allocated on heap.

Enrico Weigelt, metux IT consult 44f947b9cb (!1614) xfixes: simplify dispatcher
The dispatcher functions are much more complex than they're usually are
(just switch/case statement). Bring them in line with the standard scheme
used in the Xserver, so further steps become easier.

It's also much cleaner to use the defines from proto headers instead of
raw numbers.

Enrico Weigelt, metux IT consult eb0baa881c (!1614) xfixes: untwist Xinerama handling
The current way of switching between Xinerama and single-screen handlers
is quite complicated and needs call vector tables that are changed on
the fly, which in turn makes dispatching more complicated.

Reworking this into a simple and straight code flow, where individual request
procs just look at a flag to decide whether to call the Xinerama or single
screen version.

This isn't just much easier to understand (and debug), but also removes the need
or the call vectors, thus allowing further simplification of the dispatcher.

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.

Adam Jackson ba2432a020 xfixes: Forbid manipulating clip for source-only pictures (#28968)
Just throw BadPicture instead of crashing.  It's not currently a
meaningful thing to do anyway, RenderSetPictureRectangles would error if
you tried (which this patch changes to BadPicture as well for
consistency).  The problem with trying to do it is if the clip is
specified as a pixmap then we try to convert it to a region, and
->BitmapToRegion requires a ScreenPtr, and source-only pictures don't
have one.

I can imagine a use for client clip on source-only pictures, so if we
really wanted to allow this, probably the way forward is to always store
the clip as a region internally, and when setting the clip _from_ a
pixmap, look up BitmapToRegion relative to the pixmap not the picture.
But since clearly nobody can be relying on it working...

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

Keith Packard 2dc138922b Rename region macros to eliminate screen argument
This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.

The mechanical changes were performed by running the included
'fix-region' script over the whole tree:

$ git ls-files | grep -v '^fix-' | xargs ./fix-region

And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.

$ sh ./fix-patch-whitespace

Thanks to Jamey Sharp for the mighty fine sed-generating sed script.

The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

Paulo Cesar Pereira de Andrade 49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).
