OPENSOCKETFUNCTION documentation weirdness

From: Jeff Mears via curl-library <curl-library_at_cool.haxx.se>

The documentation for CURLOPT_OPENSOCKETFUNCTION is a little weird.

https://curl.haxx.se/libcurl/c/CURLOPT_OPENSOCKETFUNCTION.html

CURLSOCKTYPE_ACCEPT doesn't make any sense for OPENSOCKETFUNCTION, because there's no listener socket passed in. Indeed, the only code using this constant is ftp.c, which only uses the constant for the SOCKOPTFUNCTION:

  if(data->set.fsockopt) {
    int error = 0;

    /* activate callback for setting socket options */
    Curl_set_in_callback(data, true);
    error = data->set.fsockopt(data->set.sockopt_client,
                               s,
                               CURLSOCKTYPE_ACCEPT);
    Curl_set_in_callback(data, false);
