HID: wacom: Fix sensor outbounds and redefine as offsets from each edge
Many of Wacom's display tablets include an "outbound" area where pen
digitizing is possible but outside of the display area. To ensure that
pen coordinates are mapped to the correct on-screen location, the driver
sets the minimum and maximum axis values of X and Y to those coordinates
which coincide with the screen edge. These values are simply the
hardware minimum/maximum plus/minus the outbound size for a particular
edge.
When outbound support was added/updated in ac414da, fa77034, and
ecd618d, we decided to have the wacom_features structs store the desired
minimum and maximum values directly. In hindsight, this was perhaps not
the best choice since it has allowed minor errors to crop up unnoticed.
Some tablets have had their coordinates over-corrected (e.g. most of the
devices "fixed" in ecd618d were already adjusted in ac414da), while
others never had a correction applied (e.g. the ISDv5 325, whose
declared maximum the hardware maximum instead of the outbound maximum).
A less error-prone method of handling the outbound is to let the driver
calculate the correct minimum/maximum values by providing it with both
the actual hardware maximums and the size of the outbound on each edge.
These values are more easy to verify as correct since the values can be
trivially compared against specifications.
This patch reverts the declared maximum values to the actual hardware
maximums, e.g. as declared prior to ac414da (values for these and other
display tablets that were subsuquently introduced have been verified
against specs). Per-edge outbound sizes are stored in the wacom_features
struct as offset_{left,right,top,bottom} and used in combination with
the hardware ranges to calculate effective axis ranges for ABS_X and
ABS_Y.

Input: wacom - create a separate input device for pads
Currently, the pad events are sent through the stylus input device
for the Intuos/Cintiqs, and through the touch input device for the
Bamboos.
To differentiate the buttons pressed on the pad from the ones pressed
on the stylus, the Intuos/Cintiq uses MISC_SERIAL and ABS_MISC. This
lead to a multiplexing of the events into one device, which are then
splitted out in xf86-input-wacom. Bamboos are not using MISC events
because the pad is attached to the touch interface, and only BTN_TOUCH
is used for the finger (and DOUBLE_TAP, etc...). However, the user space
driver still splits out the pad from the touch interface in the same
way it does for the pro line devices.
The other problem we can see with this fact is that some of the Intuos
and Cintiq have a wheel, and the effective range of the reported values
is [0..71]. Unfortunately, the airbrush stylus also sends wheel events
(there is a small wheel on it), but in the range [0..1023]. From the user
space point of view it is kind of difficult to understand that because
the wheel on the pad are quite common, while the airbrush tool is not.
A solution to fix all of these problems is to split out the pad device
from the stylus/touch. This decision makes more sense because the pad is
not linked to the absolute position of the finger or pen, and usually, the
events from the pad are filtered out by the compositor, which then convert
them into actions or keyboard shortcuts.
For backward compatibility with current xf86-input-wacom, the pad devices
still present the ABS_X, ABS_Y and ABS_MISC events, but they can be
completely ignored in the new implementation.
