List of changes in components/wifi_provisioning: * Manager version is now v1.1 * .proto files and protocomm handler added for sending Wi-Fi scan command and receiving scan results * Implemented handlers for wifi_scan protocomm endpoint * Update manager context data structure to hold scan state and results * scheme_softap now runs Wi-Fi in APSTA mode * Wi-Fi is started in AP mode when provisioning is started. This is necessary for scan list to work * Docs updates with information about new wifi_scan endpoint List of changes in tools/esp_prov: * Added functions for sending and receiving protobuf messages compatible with wifi_scan protocomm endpoint * Added feature to display/refresh scan results and accept user selection at runtime * New functions: * get_version() : only returns the protocol version string * has_capability() : check is a capability is present according to proto-ver response * wifi_scan feature is provided only if the `wifi_scan` capability is present Other changes: * Replace recursive mutex with plain mutex * assert on return value of mutex give / take calls * replace all calls with macros ACQUIRE_LOCK and RELEASE_LOCK * some checks added in scanning related private APIs * free and nullify scanning context and state if service is stopped while ongoing scan
