At debug log level, tcpip_adapter would print logs for each function
call scheduled onto the tcpip task. These logs contained pointers which
idf_monitor decoded, adding even more noise and useless vertical space
in logs. This change moves these log statements to verbose level.
Since only the used interface's start function gets called, it pulls
in only the functions that are required in the current application,
thereby saving footprint.
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.
- put contents of a few headers into c++ guard blocks
- fix off-by-one error in do_global_ctors
- remove system_init from startup code (should be called from main)
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.
