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.

+* user mode.
+*
+* Most of these functions have two separate blocks of code that are
+* conditional on whether this is a station or an AP. This is used
+* to separate out the STA and AP responses to these management primitives.
+* It's a choice (good, bad, indifferent?) to have the code in the same
+* place so it's clear that the same primitive is implemented in both
+* cases but has different behavior.
