CHROMIUM: Override SSID logging
This is a short-term stop-gap intended to reduce PII in wpa_supplicant
logs. Because wpa_ssid_txt is generally used for logging, co-opt this
symbol to hash SSID information.
For control channel data, provide and use explicit control symbols
(i.e., wpa_ctrl_ssid_txt). To support testing, any call site that uses
both wpa_msg* and wpa_ssid_txt is converted to wpa_msg*_ctrl to avoid
logging.
Note that wpa_dbg behaves like wpa_msg, but it can be removed from build
to reduce binary size. As such, it is not a control interface and does
not require update.
