I thought some more about 2 and 3.  Why not make the init deinit automatic,
much as it is now for hostapd.  We can remove the global init/destruct
hooks for nl80211 and just let the driver take care of creating the global
struct when the first device is added, and destruct when the last one is

There is no reason that I know of to open the sockets and such if we
have no devices actually using that driver.

If you are OK with that, then I can either re-work the patches slightly
to do this, or we could apply them as they are and I'll post follow-up patches
to make the changes.  I think it's mostly correct now except the driver
doesn't ever deinit itself in hostapd mode.  In practice, I doubt this
will be a problem, especially if it's soon fixed properly.
