docs/libcurl/opts: clarify the return values

Expand a little.

- mention the type name of the return code
- avoid stating which exact return codes that might be returned, as that
  varies over time, builds and conditions
- avoid stating some always return OK
- refer to the manpage documenting all the return codes

Closes #15900

NAME

CURLOPT_SASL_AUTHZID - authorization identity (identity to act as)

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SASL_AUTHZID, char *authzid);

DESCRIPTION

Pass a char pointer as parameter, which should be pointing to the null-terminated authorization identity (authzid) for the transfer. Only applicable to the PLAIN SASL authentication mechanism where it is optional.

When not specified only the authentication identity (authcid) as specified by the username is sent to the server, along with the password. The server derives a authzid from the authcid when not provided, which it then uses internally.

When the authzid is specified, the use of which is server dependent, it can be used to access another user's inbox, that the user has been granted access to, or a shared mailbox for example.

The application does not have to keep the string around after setting this option.

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

DEFAULT

blank

    curl_easy_setopt(curl, CURLOPT_USERNAME, "Kurt");
    curl_easy_setopt(curl, CURLOPT_PASSWORD, "xipj3plmq");
    curl_easy_setopt(curl, CURLOPT_SASL_AUTHZID, "Ursel");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
