Patch by idefix: Code cleanup and debug output cleanup. Part of patch to
ticket #3744, thanks!

When canceling the transfer, the callback is still called, just with the
canceled status, so we need to collect the corresponding sem release. Otherwise
we would run directly into the old cancel status the next time we schedule.

I don't know why this was disabled, but not canceling the queued transfers after
a timeout leaks these transfers. In the end this would at least lead to a flood
of canceled transfers on device unplug or, worse yet, exhaust the USB memory
pool stalling all further transfers as seen in #4604. Probably fixes both
issues, can't test though as I don't have the hardware.

Whitespace cleanup only, no functional change.

Patch by idefix:
* Use the correct interface index for the control transfer that sets a Wacom
tablet into tablet mode.
* Check if the mode is indeed setup correctly.
* Retry switching the mode up to five times, as done in the Linux driver.

Thanks a bunch! As Michael has proposed in ticket #3744, the whole Wacom
driver should be merged into the existing HID driver framework (eventually).

* Cleanup for 80 char per line limit.
* Don't spam the syslog when the device was not a Wacom.

Made sure load_driver_symbols() is not used anymore when building for Haiku;
it's a no-op, and I removed the prototype from KernelExport.h.

* Small cleanups, renamed "md" (for "mouse device") to "device" among other
stuff.
* It's a while since I wrote this code, and I don't remember why I don't
always "set the configuration". Appearantly on BeOS and ZETA, the
active configuration was not yet set on the device when the driver examined
it, but on Haiku it is. The special control command which puts a tablet
into tablet mode is then not executed. I simply commented out this check
(always set the configuration) and now my Wacom Intuos 2 is working fine
in Haiku.

* added a kernel driver for Wacom USB tablets.
* the driver should be generic for all Wacom tablets, but there is a
special control transfer to put the devices in to "absolute mode", it
may not work with future tablets. The driver allows to use read devices,
for which there is a special protocol. If the read request has a certain
size, then the driver will transmit info on the device, like the vendor
and product id as well as the max the packet size, for reads larger than
that, it will issue an interrupt transfer and put the raw data received
from the device behind the info header
