Enrico Weigelt, metux IT consult f39bbe58d6 exa: use PixmapDestroy hook
Wrapping ScreenRec's function pointers is problematic for many reasons,
so use the new pixmap destroy notify hook instead.

Enrico Weigelt, metux IT consult ee798cf212 exa: simplify CreatePixmap()/DestroyPixmap() handlers error pathes
Instead of complex wrap/unwrap trickery in the error path, just
protect the DestroyPixmap() handlers from half-initialized state.

Prior to this change, we always had to make sure, the we're calling
the original (screen driver's) handler directly, instead of our own
(which calls the original one, too), so it doesn't do any damage.
This isn't necessary anymore, since it finds out on it own what to do.

This not just makes the code flow simpler and easier to understand, but
also clears the road for decoupling the extension specific pixmap destructor
logic from the ScreenRec proc vectors (*1).

Enrico Weigelt, metux IT consult ef62929f58 treewide: NULL-protect ScreenRec->DestroyPixmap() calls
Right now, we're assuming that even when deep nesting involved, the proc
vector is always set to a valid function. One the one hand it requires
extra dummy procs in some cases, OTOH it's making upcoming refactoring
of the code flow unnecessarily complex.

The big plot (of subsequent commits) is splitting out the extension's
(and possibly subsystem's) special logic out of the wrapping chain and
let them be executed independently from the DDX/drivers - when applicable
even only when the pixmap is really destroyed (not just unref'ed).
(At some later point, it might even become be actually a valid situation
that DestroyPixmap vector really being NULL.)

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.

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.

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 d5b16b037b Revert "dix: Remove usage_hint from pixmaps, store it in ->drawable.class"
This reverts commit 1564c82417.

The drivers used the top bits of the usage_hint to store driver
private flags (intel, radeon, nouveau).

With EXA we need to get at this data so if we migrate the pixmap we
can create the correct type of pixmap in the driver, however this
commit truncates the usage_hint into 8-bit class and loses all the
good stuff.
