Adam Jackson 4e101e7e3b mi: Simplify a conditional in miHandleExposures
miHandleExposures does two things: computes the region for which to
generate expose events, and (if the destination is a window) paints the
exposed regions with the background. The bit of this conditional we're
deleting here asserts that the source is either a pixmap or a window
without backing store. The only other possibility is a window _with_
backing store. In the old backing store implementation, this was where
you would recover bits from backing store. Since our "backing store" is
the redirected window pixmap, we know we've already copied all we could,
because CopyArea had already seen the entire window pixmap. So now in
that third case, we are still drawing to a pixmap (so there's no
background to paint) and we are still not generating events, so we can
exit early.

The comment above the function about recovering bits from backing store
is clearly misleading, so delete that too.

Adam Jackson 74d64ceea0 mi: Remove questionable optimization from the rootless path
This is effectively a revert of 7b506fdc84
except the coding style reindent broke that.  The code makes no sense in
any case.  drawable can never be null since it's the first member of
WindowRec, and we're never called with a null window.  Neither can it be
an UNDRAWABLE_WINDOW since those are InputOnly windows; the rootless
code does not set the root window to either UNDRAWABLE or InputOnly, so.

Peter Harris b4061cf5f7 Fix border tile origin when background is ParentRelative
According to
http://www.x.org/releases/X11R7.7/doc/xproto/x11protocol.html#requests:CreateWindow
"The border tile origin is always the same as the background tile
origin."

ChangeWindowAttributes goes to some effort to make sure it repaints
the border tile whenever the background origin may have changed, but
miPaintWindow was ignoring the background origin.

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

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.

Jamey Sharp a83cff9f4d Move each screen's x/y origin into ScreenRec.
Many references to the dixScreenOrigins array already had the
corresponding screen pointer handy, which meant they usually looked like
"dixScreenOrigins[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 declared the dixScreenOrigins array, I figure allocating a
screen private for these values is overkill.

Jamey Sharp e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.

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

xf86-video-dummy currently uses WindowTable, so it needs to be updated

all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.

Looks like Xproto.h dropped them by X11R6.3, which didn't have

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).

Paulo Cesar Pereira de Andrade d6cbd4511e Export symbols defined in the sdk.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

  Symbols in the sdk (or referenced in sdk macros), but not defined
