   Fix REAUTHENTICATE command after PMKSA caching

   The current PMKSA cache entry needs to be clear to allow EAPOL
   reauthentication to be started in case this association used PMKSA
   caching.

 - Remove old WPS_OOB NCF
 - WPS: Add preliminary NFC connection handover support for Enrollee
 - WPS: Reenable the networks disabled during wpa_wpas_reassoc
 - P2P: Avoid multi-channel scans when they are not needed
 - P2P: Allow discoverable interval for p2p_find to be configured
 - P2P: Allow all channels with multi-channel concurrency
 - Bonjour changes
 - Remove disassociate
 - HS 2.0 changes
 - Add preliminary support for using SQLite for eap_user database
 - Add SAE support
 - Add disallow_aps parameter to disallow BSSIDs/SSIDs
