[PATCH] divide usb83xx.ko into lib83xx.ko and usb83xx.ko

divide usb83xx.ko into lib83xx.ko and usb83xx.ko
Quite crude right now
Signed-off-by: Holger Schurig <hs4233 at mail.mn-solutions.de>
---
This patch still creates a usb83xx.ko module, but also a lib83xx.ko
module. That is similar to orinoco_cs.ko and orinoco.ko.
In the long run, more core should go from main_usb.c into libertas.c.
This would then also reduce the rather long EXPORT_SYMBOL() list in
libertas.c
