nl80211/cfg80211: WoWLAN support
This is based on (but now quite far from) the original work from Luis and Eliad. Add support for configuring WoWLAN triggers, and getting the configuration out again. Changes from the original patchset are too numerous to list, but one important change needs highlighting: the suspend() callback is passed NULL for the trigger configuration if userspace has not configured WoWLAN at all.
