Add SME support (separate authentication and association) This can be used, e.g., with mac80211-based Linux drivers with nl80211. This allows over-the-air FT protocol to be used (IEEE 802.11r). Since the nl80211 interface needed for this is very recent (added today into wireless-testing.git), driver_nl80211.c has backwards compatibility code that uses WEXT for association if the kernel does not support the new commands. This compatibility code can be disabled by defining NO_WEXT_COMPAT. That code will also be removed at some point to clean up driver_nl80211.c.

SME: Deauthenticate to clear state after disassociation events cfg80211/mac80211 can get into somewhat confused state if the AP only disassociates us and leaves us in authenticated state. For now, force the state to be cleared with deauthentication to avoid confusing errors if we try to associate with the AP again. This gets rid of 30 second delay (scan timeout) in cases where only a disassociation frame is received from the AP.

Use SA Query procedure to recovery from AP/STA state mismatch If a station received unprotected Deauthentication or Disassociation frame with reason code 6 or 7 from the current AP, there may be a mismatch in association state between the AP and STA. Verify whether this is the case by using SA Query procedure. If not response is received from the AP, deauthenticate. This implementation is only for user space SME with driver_nl80211.c.
