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.

+*  While this file is called 'ioctl' is purpose goes a little beyond
+*  that.  This file defines the types and contants used to implement
+*  the p80211 request/confirm/indicate interfaces on Linux.  The
+*  request/confirm interface is, in fact, normally implemented as an
+*  ioctl.  The indicate interface on the other hand, is implemented
+*  using the Linux 'netlink' interface.
+*
+*  The reason I say that request/confirm is 'normally' implemented
+*  via ioctl is that we're reserving the right to be able to send
+*  request commands via the netlink interface.  This will be necessary
+*  if we ever need to send request messages when there aren't any
+*  wlan network devices present (i.e. sending a message that only p80211
+*  cares about.
