This patch introduces struct wiphy and struct wireless_dev. The latter
is added to struct net_device as ieee80211_ptr and keeps wireless per-netdev
state, the wiphy keeps wireless per-device (hardware) state and is
accessible from struct wireless_dev.

I think we should go with this for now. I've tested it quite a bit and
it all seems to work pretty well.
For the future:
Maybe instead of having ieee80211_ptr point to a struct wireless_dev
(which can be allocated along with the netdev) we should mandate that
each wireless netdev is allocated via a new function that puts the
wireless_dev struct as the first part of the private area of the netdev,
that way getting to it is just a simple addition instead of following
a pointer... and we can also drop ieee80211_ptr from struct net_device.
We'd provide functions to go from netdev to wdev and from wdev to
priv. Also, we could then keep track of all wdevs that have been added
to a certain wiphy and get rid of the cfg80211 list_interfaces callback.
And we could pass a wdev to all calls there...
Another thing to do is allowing renaming of the wiphy via cfg80211...
Well, if anybody read this far I'd appreciate comments, if not, well,
who cares? :)
