Staging: add wlan-ng prism2 usb driver

This adds the wlan-ng prism2 USB driver to the drivers/staging tree.

The code was originally written by the linux-wlan-ng team, patched by
some Novell engineers to properly work on newer kernels, and then hacked
into place in order to get it to build properly in a single subdirectory
within the kernel tree by me.

It supports a wide range of older USB prism2 devices, and contains a
80211 stack to support this single driver.

+*
+*  The reason I say that request/confirm is 'normally' implemented

+*  request commands via the netlink interface.  This will be necessary
+*  if we ever need to send request messages when there aren't any
