Intuos5 tablets with PTH-* model numbers include a multitouch sensor
which use the same touch reports as the 3rd-generation Bamboo. No
useful information is in the HID descriptor for the touch interface
so hardcoded values are used during setup.

When a tablet connect or disconnect is detected, schedule
work queue to register or unregister related input devices.

When a wireless tablet connects, it reports same USB PID
used if tablet is connected with USB cable. Use this to
update features values, set input capabilities, and then
register device.  From there, the Pen and Touch interfaces
will reuse the existing tablet's IRQ routines.

Its possible that 1 receiver is shared with 2 tablets with
different PID (small and medium Bamboo for example) so the
input is unregister at disconnect to better support this case.

The 3rd gen Bamboo Pen & Touch and Intuos5 tablets support an
optional wireless module. When its receiver is plugged into USB,
it presents 3 interfaces: 0) Monitor 1) Pen and 2) Touch.

The exact capabilities of the Pen and Touch interfaces can
not be determined until a tablet connection is established
and reported over the Monitor interface.

This patch detects this wireless receiver and enables interrupt
packets to be processed for the Monitor interface. Processing
the data in packets will be left to another patch.

Since it doesn't make sense to create an input device for the
Monitor interface, it is not created. Creation of Pen and Touch
input device is also delayed until monitor packets can be processed.

This calculation determines the physical dimensions of the tablet,
used later on in calculate_touch_res to obtain the touch sensor
resolution.

Instead of dividing the logical size by the resolution, the current
code performs a multiplication. This doesn't pose a problem for the
3rd-gen Bamboo since the resolution and scale factor happen to be
identical, but will produce an incorrect result for other cases.

Bamboo's Pen and Touch packets always start with a value
of 0x02 in first byte.  In 3rd gen Bamboo's, the hw is now
periodically sending some additional packets with unrelated data
and uses a value other than 0x02 to inform driver this.

Ignore those packets now.

This was reported by users as bad behavior in Gimp. The
invalid packets being processed made the stylus report
out of proximity for the 1 packet and this triggered some
secondary bug which caused Gimp to stop drawing until
user really took pen out of proximity of tablet.

in touch 1 pressure field.  They also report 2nd touch X/Y values
shifted down 1 byte (where pressure was).  This results in jumpy

For touch detection, switch to a Touch Present single bit that
