WPS: Maintain more AP state during WPS PIN iteration Maintain state of WPS APs during iteration to find the correct AP for WPS PIN operation when no specific BSSID is specified. This information can be used for optimizing the order in which the APs are tried.

WPS: Add support for AP reconfiguration with wps_reg wpa_supplicant can now reconfigure the AP by acting as an External Registrar with the wps_reg command.

WPS: Use different scan result sorting rules when doing WPS provisioning The AP configuration may change after provisioning, so it is better not to use the current security policy to prioritize results. Instead, use WPS Selected Registrar attribute as the main sorting key and use signal strength next without considering security policy or rate sets. The non-WPS provisioning case remains as-is, i.e., this change applies only when trying to find an AP for WPS provisioning.
