Set a destructor function on pixman images and call fbFinishAccess()
from there, rather than directly from free_pixman_pict(). This ensures
that fbFinishAccess() gets called even if pixman still has a reference
to the image after free_pixman_pict(), as is the case for alphamaps.

This does have one semantic change. FixesCreateRegionFromPicture used to
throw BadImplementation if you tried to create a region from a picture
with no client clip. I changed that to BadMatch here since that more
honestly describes what's going on.

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

The only user of the geometry coordinates is the software sprite code,
which uses them to remove the pointer whenever the window beneath is
being used as a source. However, using Window pictures as a source is
extremely rare (let alone *partial* windows), so there is no harm done
in just validating all of the drawable.
Additionally, the miSourceValidate() function was buggy in at least
three respects:
(a) It added drawable->{x,y} before calling down, which is wrong since
the misprite code already adds them in its check. (Alternatively,
the misprite code is wrong, but there are actual users who would
notice if that code was broken).
(b) It didn't account for the width of the interpolation filter, so if
the Picture had a bilinear or convolution filter, the edges
surrounding the source area would not be validated.
(c) It didn't validate alpha maps.
Finally, computing the bounding box of the transform on every
composite request was a real performance issue in pixman, so
presumably it could be one here as well.
This patch changes miSourceValidate() to simply validate all of the
underlying drawable.

The main consumer of trapezoids, cairo, is using the Trapezoids
request, which is currently implemented in the miTrapezoids()
function. That function splits the request into smaller bits and calls
lower level functions such as AddTrap.
By moving the implementation of the whole request into fb, we can
instead call pixman_composite_trapezoids() to do the whole request in
one step.
There are no callers of miTrapezoids in any of the open source
drivers, although exa and uxa have their own copies of the function.

Recursive alpha maps (where one picture's alpha map is set to a
picture with an external alpha map) would be all fine and dandy,
except for the case where the client constructs a loop. Detecting this
case when setting the alpha map values would be difficult as any time
an alpha map is set, the server would have to check for the looping
case.
Instead, a far simpler fix is to simply disallow recursive alpha maps
in the rendering code, the Render spec is ambiguous in this area and
allows us to to ignore the recursive case.

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.

Windows (or even pixmaps, in some cases) may not sit at the origin of
the containing pixmap, so any coordinates relative to the drawable
must be adjusted. For destinations and untransformed sources, the
operation coordinates are adjusted. For transformed sources, the
transform matrix is adjusted.

The new clipping rules:
- client clips happen after transformation
- pixels unavailable due to the hierarchy are undefined
The first one is implemented in pixman; the second one is realized by
making a copy of window sources (to prevent out-of-bounds access).
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).
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
anywhere include:
