This patch only changes the API, not the implementation of the
devPrivates infrastructure. This will permit a new devPrivates
implementation to be layed into the server without requiring
simultaneous changes in every devPrivates user.

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.

For absolute input devices (E.G. touchscreens) in multi-head setups,
we need a way to bind the device to an randr output. This adds the
infrastructure to the server to allow us to do so.
positionSprite() scales input coordinates to the dimensions of the shared
(total) screen frame buffer, so to restrict motion to an output we need to
scale/rotate/translate device coordinates to a subset of the frame buffer
before passing them on to positionSprite.
This is done here using a 3x3 transformation matrix, which is applied to
the device coordinates using homogeneous coordinates, E.G.:
[ c0 c1 c2 ] [ x ]
[ c3 c4 c5 ] * [ y ]
[ c6 c7 c8 ] [ 1 ]
Notice: As input devices have varying input ranges, the coordinates are
first scaled to the [0..1] range for generality, and afterwards scaled
back up.
E.G. for a dual head setup (using same resolution) next to each other, you
would want to scale the X coordinates of the touchscreen connected to the
both heads by 50%, and translate (offset) the coordinates of the rightmost
head by 50%, or in matrix form:
left: right:
[ 0.5 0 0 ] [ 0.5 0 0.5 ]
[ 0 1 0 ] [ 0 1 0 ]
[ 0 0 1 ] [ 0 0 0 ]
Which can be done using xinput:
xinput set-prop <left> --type=float "Coordinate Transformation Matrix" \
0.5 0 0 0 1 0 0 0 1
xinput set-prop <right> --type=float "Coordinate Transformation Matrix" \
0.5 0 0.5 0 1 0 0 0 1
Likewise more complication setups involving more heads, rotation or
different resolution can be handled.

Peter wants to get a larger patch sequence put together and I didn't
read past the commit message to see the 'don't take this patch
please'.
This reverts commit 531ff40301.
Some input drivers need to implement an internal hotplugging scheme for
dependent devices to provide multiple X devices off one kernel device file.
Such dependent devices can be added with NewInputDeviceRequest() but they are
not removed when the config backend calls DeleteInputDeviceRequest(),
leaving the original device to clean up.
Example of the wacom driver:
config/udev calls NewInputDeviceRequest("stylus")
wacom PreInit calls
NewInputDeviceRequest("eraser")
NewInputDeviceRequest("pad")
NewInputDeviceRequest("cursor")
PreInit finishes.
When the device is removed, the config backend only calls
DeleteInputDeviceRequest for "stylus". The driver needs to call
DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to
clean up properly.
However, when the server terminates, DeleteInputDeviceRequest is called for
all devices - the driver must not remove the dependent devices to avoid
double-frees. There is no method for the driver to detect why a device is
being removed, leading to elaborate guesswork and some amount of wishful
thinking.
Though the input driver's UnInit already supports flags, they are unused.
This patch uses the flags to supply information where the
DeleteInputDeviceRequest request originates from, allowing a driver to
selectively call DeleteInputDeviceRequest when necessary.
Also bumps XINPUT ABI.

The XI protocol spec only allows for two errors on the SetDeviceMode
requests: BadMatch or BadMode. BadMode however is a dynamically assigned
extension error and the driver doesn't have access to the actual error
number. Hence, if a SetDeviceMode driver returns an error other than
BadMatch, assume BadMode.
The two exceptions are BadAlloc and BadImplementations, pass these on to the
client (any request is allowed to return either of those).

If the indicator flags have the XkbSLI_IsDefault bit set, the indicator map
and names aren't their own bit of memory but rather point into the
device->key->xkbInfo->desc structure. XkbCopySrvLedInfo knows about this and
leaves the pointers alone.
When copying the classes from the slave to the master, these pointers are
copied and still point to the dev->key class of the slave device. If the
slave device is removed, the memory becomes invalid and a call to modify
this data (e.g. XkbSetIndicators) may cause a deadlock.
The copying of dev->key relies on dev->kbdfeed to be already set up. Hence
the pointers need to be reset once _both_ kbdfeed and key have been copied
into the master device.
