2b875e18bc Xi: consolidate request handler prototypes
Instead of having huge number of micro-headers, consolidate all the
request handler prototypes in one file.

95959758dc Xi: drop including <dix-config.h> from internal headers
All their consumers need to include <dix-config.h> at the very top anyways.

42daf8e53e Xi: drop using HAVE_DIX_CONFIG_H
This symbol is always defined, and the header is always present,
so no need to check for it.

5bf2f662cc XI: directly write out X_XIQueryDevice reply
Write out the X_XIQueryDevice  reply directly (and do the swapping
within the request handler) instead of going through separate callback
that's having demux the replies again.

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

3fb258ca28 input: add a TouchClassRec to the devices
These structs will be used to store touch-related data, events and
information.

Drivers must call InitTouchClassDeviceStruct to set up a multi-touch capable
device.

Touchpoints for the DDX and the DIX are handled separately - touchpoints
submitted by the driver/DDX will be stored in the DDXTouchPointInfoRec. Once
the touchpoints are processed by the DIX, new TouchPointInfoRecs are created
and stored. This process is already used for pointer events with the
last.valuators field.

Note that this patch does not actually add the generation of touch events,
only the required structs.

TouchListeners are (future) recipients of touch or emulated pointer events.
Each listener is in a state, depending which event they have already
received. The type of listener defines how the listener got to be one.

3304bbff9b Input: Add smooth-scrolling support to GetPointerEvents
For scroll wheel support, we used to send buttons 4/5 and 6/7 for
horizontal/vertical positive/negative scroll events.  For touchpads, we
really want more fine-grained scroll values.  GetPointerEvents now
accepts both old-school scroll button presses, and new-style scroll axis
events, while emitting both types of events to support both old and new
clients.

This works with the new XIScrollClass to mark axes as scrolling axes.
Drivers mark any valuators that send scroll events with SetScrollValuator.
(Currently missing: the XIDeviceChangeEvent being sent when a driver changes
a scroll axis at run-time. This can be added later.)

Note: the SCROLL_TYPE enums are intentionally different values to the XI2
proto values to avoid copy/overlapping range bugs.

8502c06e19 xace: Fake return values on denials in input polling requests.
Instead of returning BadAccess when "read" permission is denied
on a device, falsify the device state (buttons down, keys pressed).
This is nicer to applications, but may still have undesired side
effects.  The long-term solution is not to use these requests in
event-driven code!

Requests affected: QueryPointer, QueryKeymap, XiQueryDevice.

d230742ea8 Xi: namespace XI2 files.
Some files (notably those merged with MPX before XI2 came along) didn't use
a 'xi' prefix. This patch changes all of them to meaningful names.
