1. Modify sta to station in comments
2. Modify esp_wifi_get_ap_num to esp_wifi_scan_get_ap_num
3. Modify esp_wifi_get_ap_list to esp_wifi_scan_get_ap_records
While this may reduce esp_wifi.h file readability for people who don't have a "go to definition" function in their editors, this is needed to decouple esp_wifi and esp_event headers, and possibly other headers which may use wifi types in the future.
This change removes implicit WiFi/BT initialization from startup code.
"main" task is started once essential part of startup code is complete.
This task calls application-provided "int main(void)" function, which can call WiFi/BT init functions if necessary.
1. Add the parameter type of api esp_wifi_set_storage.
2. WIFI_STORAGE_RAM means storing profiles in ram. WIFI_STORAGE_FLASH means storing profiles in flash.
The parameter aid followed -a is aid of the connected station. If aid is 0, kick out all of the connected stations.
2. Add block parameter to api esp_wifi_scan_start.
If block is true, the api blocks before scan done or returns directly.
2. Add struct station_list into tcpip_adapter layer
3. When ap -L cmd is received, get mac address from mac layer first and then search ip address based on mac address on dhcp layer.
