[PATCH] Update of USB input drivers to the latest versions 

Now that the input core changes have made it into 2.5 I can finally
update the USB input drivers to their latest versions.

Here is a patch that does that.

In detail:

	HID driver:
		Fix a bug in descriptor parsing (array/variable),
			namely visible with Logitech new joysticks and mice
		Fix bugs in logical/physical min/max parsing
		Fix bugs in exponent parsing
		Remove workaround for low-speed devices with >8 byte
			reports, fix this in a correct way (bigger irq
			request)
		Untangle some code (fetc_item())
		Implement asynchronous input/output/feature report
			reading and writing
		Implement (hopefully) proper locking in the above
		Implement support for devices with an output endpoint
		Add some support functions for force feedback support
			currently in development
		Add entries to the debug dump code, including FF and
			exponents
		Add more mappings into the hid-input interface
		Cleanups here and there

	usbkbd driver:

		Make LED URBS use GFP_ATOMIC, they'll be called from a
			completion handler
		Remove dependency on hid.h

	usbmouse driver:

		Just conversion to the new input core, minor cleanups

	wacom driver:

		Just conversion to the new input core.
