USB: wacom tablet driver reorganization

Browse Source 
- split wacom.c into 4 files: wacom.h, wacom_wac.h, wacom_sys.c, and wacom_wac.c
- where wacom_sys.c deals with system specific code, 
- and wacom_wac.c deals with Wacom specific code

* ChangeLog:
* v0.1 (vp) - Initial release
* v0.2 (aba) - Support for all buttons / combinations
* v0.3 (vp) - Support for Intuos added
* v0.4 (sm) - Support for more Intuos models, menustrip
* relative mode, proximity.
* v0.5 (vp) - Big cleanup, nifty features removed,
* they belong in userspace
* v1.8 (vp) - Submit URB only when operating, moved to CVS,
* use input_report_key instead of report_btn and
* other cleanups
* v1.11 (vp) - Add URB ->dev setting for new kernels
* v1.11 (jb) - Add support for the 4D Mouse & Lens
* v1.12 (de) - Add support for two more inking pen IDs
* v1.14 (vp) - Use new USB device id probing scheme.
* Fix Wacom Graphire mouse wheel
* v1.18 (vp) - Fix mouse wheel direction
* Make mouse relative
* v1.20 (fl) - Report tool id for Intuos devices
* - Multi tools support
* - Corrected Intuos protocol decoding (airbrush, 4D mouse, lens cursor...)
* - Add PL models support
* - Fix Wacom Graphire mouse wheel again
* v1.21 (vp) - Removed protocol descriptions
* - Added MISC_SERIAL for tool serial numbers
* (gb) - Identify version on module load.
* v1.21.1 (fl) - added Graphire2 support
* v1.21.2 (fl) - added Intuos2 support
* - added all the PL ids
* v1.21.3 (fl) - added another eraser id from Neil Okamoto
* - added smooth filter for Graphire from Peri Hankey
* - added PenPartner support from Olaf van Es
* - new tool ids from Ole Martin Bjoerndalen
* v1.29 (pc) - Add support for more tablets
* - Fix pressure reporting
* v1.30 (vp) - Merge 2.4 and 2.5 drivers
* - Since 2.5 now has input_sync(), remove MSC_SERIAL abuse
* - Cleanups here and there
* v1.30.1 (pi) - Added Graphire3 support
* v1.40 (pc) - Add support for several new devices, fix eraser reporting, ...
* v1.43 (pc) - Added support for Cintiq 21UX
* - Fixed a Graphire bug
* - Merged wacom_intuos3_irq into wacom_intuos_irq
* v1.44 (pc) - Added support for Graphire4, Cintiq 710, Intuos3 6x11, etc.
* - Report Device IDs
* v1.45 (pc) - Added support for DTF 521, Intuos3 12x12 and 12x19
* - Minor data report fix
* v1.46 (pc) - Split wacom.c into wacom_sys.c and wacom_wac.c,
* - where wacom_sys.c deals with system specific code,
* - and wacom_wac.c deals with Wacom specific code
