- Reports the current status of the battery (discharging, cherging, full).
- Also notify the upower daemon when there is a change in the battery
value.
- keep the battery value as a percentage, not the raw value

The current implementation uses "wacom_battery" as a generic name for
batteries. This prevents us to have two Wacom devices with a battery
attached as the power system will complain about the name which is already
registered.
Use a specific name for each type of battery attached.
A bug in upower prevents us to use spaces in the power name, so replace
each space by '_'.

Now that wacom is a hid driver, there is no point in having a separate
driver for bluetooth device.
First, merge the Graphire BT tablet.

Now that wacom is a hid driver, there is no point in having a separate
driver for bluetooth devices.
Another good point of this is that now, the Intuos4 bluetooth can handle
the different tools (artpen, airbrush), and we get a common interface
between USB and BT for accessing the LEDs/OLEDs.

Bluetooth Wacom tablets are now handled by the regular wacom.ko driver.
Remove the now useless hid-wacom driver.

Both tablets that I had (Graphire Wireless and Intuos4 Wireless)
supports slow and fast reporting. Slow reporting is necessary with older
bluetooth receivers otherwise the lag between pen movement and cursor
movement made devices unusable.
I tried to expose all events reported by hardware and I think AC
reporting should stay in the kernel.

Ok, I'll send a v2 next week with these two things fixed.

Benjamin,
I think we might try to fix that [1] as well when making changes to the
sysfs entries. Currently every tablet connected wirelessly will trigger
creating new sysfs entries:
/sys/class/power_supply/wacom_ac
/sys/class/power_supply/wacom_battery
so sysfs is not happy about attempts to create duplicates. We need to
distinguish between devices using consecutive numbers or something else.

Right. In this first attempt, I tried to change "wacom_" by the actual
name of the tablet. I would thought it was OK because no one will ever
try to plug the same model twice. I was wrong, and a counter seem to be
the solution for that. I'll address that in the v2.
Also note that the bug is both in the current USB driver (wacom.ko) and
the bluetooth one (hid-wacom.ko). Merging these two drivers will prevent
us to have to do this fix twice :)
Just as a head up, I will not be able to work on this patch series
before Thursday (I mean testing with actual hardware). I'd be happy if
we can manage to push that in 3.17, but this will mostly depend if
Dmitry is fine with the USB-to-HID conversion of the wacom.ko driver.
Cheers,
Benjamin
