CURLOPT_HTTP200ALIASES.3: Mainly SHOUTcast servers use "ICY 200"

Browse Source 
Icecast versions 1.3.0 through 1.3.12 would reply with "ICY 200"
under certain conditions:

    client_wants_icy_headers (connection_t *con)
    {
            const char *val;

            if (!con)
                    return 1;

            val = get_user_agent (con);
            if (!val || !val[0] || strcmp (val, "(null)") == 0)
                    return 1;

            if (con->food.client->use_icy)
                    return 1;
            if (strncasecmp (val, "winamp", 6) == 0)
                    return 1;
            if (strncasecmp (val, "Shoutcast", 9) == 0)
                    return 1;

            return 0;
    }

So mainly if there is no 'user agent' or it is '(null)' or contains
'winamp' or 'Shoutcast'.

No mainstream distribution carries Icecast 1.3.x anymore, after all
it was released in 2002 and superseded by Icecast 2.x.

.SH DESCRIPTION
Pass a pointer to a linked list of \fIaliases\fP to be treated as valid HTTP
200 responses. Some servers respond with a custom header response line. For
example, IceCast servers respond with "ICY 200 OK". By including this string
in your list of aliases, the response will be treated as a valid HTTP header
line such as "HTTP/1.0 200 OK".
example, SHOUTcast servers respond with "ICY 200 OK". Also some very old
Icecast 1.3.x servers will respond like that for certain user agent headers or
in absence of such. By including this string in your list of aliases,
the response will be treated as a valid HTTP header line such as
"HTTP/1.0 200 OK".
The linked list should be a fully valid list of struct curl_slist structs, and
be properly filled in. Use \fIcurl_slist_append(3)\fP to create the list and
