Centers the ABS_TILT_{X,Y} axes so that a value of zero is reported when
the pen is vertical. Combined with resolution information in the next
patch, this makes it possible for userspace to calculate the pen angle

was updated to support signed tilt values in late-2012 (2f2acec).

ISDv4 and v5 are plain HID devices. We can directly implement a generic
HID parsing/handling and remove the need to manually add those PID in
the list of supported devices.

This patch implements the pen support only. The finger part will come in
a later patch.

To be properly notified of an .event() and a .report(), we need to force
hid-core to go through the HID parsing. By default, wacom.ko binds only
hidraw, so the hid parsing is not done by hid-core. When a true HID device
is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will
force hid-core to parse the incoming reports.
(Note that this can be easily backported by directly setting the .claimed
flag to HID_CLAIMED_DRIVER even if hid-core does not support
HID_CONNECT_DRIVER)

Currently, tablets connected to the WL receiver all share the same
VID/PID. There is no way for the user space to know which one is which
besides parsing the name. We can force the PID to be set to the
actual hardware. This way, the input device will have the correct PID
which can be match in libwacom.

With only this trick, the pad input does not inherit the ID_INPUT_TABLET
udev property from its parent. We can force udev to accept it by declaring
a BTN_STYLUS which is never used.

This way, tablets connected through WL can be used from the user point of
view in the same way they are used while connected through wire.

All USB Wacom tablets are actually HID devices.
For historical reasons, they are handled as plain USB devices.
The current code makes more and more reference to the HID subsystem
like implementing its own HID report descriptor parser to handle new
devices.

From the user point of view, we can transparently switch from this state
to a driver handled in the HID subsystem and clean up a lot of USB specific
code in the wacom.ko driver.

The other benefit once the USB dependecies have been removed is that we can
use a tool like uhid to make regression tests and allow further cleanup or
new implementations without risking breaking current behaviors.

To match the current handling of devices in wacom_wac.c, we rely on the
hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when
it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the
device is plain HID. There is thus a one to one matching between the list
of supported devices before and after the switch from USB to HID.

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.

This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found
on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These
tablets use a new report ID (3) for their touch packets and a slightly
different HID descriptor format, but are otherwise largely identical in
protocol to the "MTTPC" tablets.

Note:
 * The R12 uses its 0x4004 sensor for touch input only. A pen interface
   is not present in its HID descriptor, though its possible a 0x4004
   may be used for pen input by other tablet PCs in the future.

 * The 0x5002 sensor appears to use a new report ID (8) for its pen
   packets. The other sensors continue to use the traditional report
   ID (2).
