[PATCH] add EXPORT_SYMBOL_GPL_FUTURE() to USB subsystem

The USB core symbols will be converted to GPL-only in a few years.  Mark
this as such and update the documentation explaining why, and provide a
pointer for developers to receive help if they need it.

+What:   USB driver API moves to EXPORT_SYMBOL_GPL
+When:   Febuary 2008
+Files:  include/linux/usb.h, drivers/usb/core/driver.c
+Why:    The USB subsystem has changed a lot over time, and it has been
+        possible to create userspace USB drivers using usbfs/libusb/gadgetfs
+        that operate as fast as the USB bus allows.  Because of this, the USB
+        subsystem will not be allowing closed source kernel drivers to
+        register with it, after this grace period is over.  If anyone needs
+        any help in converting their closed source drivers over to use the
+        userspace filesystems, please contact the
+        linux-usb-devel@lists.sourceforge.net mailing list, and the developers
+        there will be glad to help you out.
