fixing the icecast unicode bug

Icecast has an issue in how it parses http queries containing unicode. The query is escaped twice, so instead of having あ appear as あ it's converted to あ.

I am very new to sepples, but I need this patched within 4 days from now, and seeing how the icecast forums won't let me register I have decided to try fixing it myself.

const char *httpp_get_query_param(http_parser_t *parser, const char *name)
{
    http_var_t var;
    http_var_t *found;
    void *fp;

    fp = &found;
    var.name = (char *)name;
    var.value = NULL;

    if (avl_get_by_key(parser->queryvars, (void *)&var, fp) == 0)
        //return found->value;
       
        // ED PRETENDING HE KNOWS SEPPLES
        int durr = 0;
        char* derp, hurr;
        derp = found->value;
        for (int a = 0; derp[a]!=0; a++) {
            hurr[durr] = derp[a];
            if (derp[a+0]=='&' &&
                derp[a+1]=='a' &&
                derp[a+1]=='m' &&
                derp[a+1]=='p' &&
                derp[a+1]==';' &&
                derp[a+1]=='#') {
                a += 4;
            }
            durr++;
        }
        return hurr;
        // END OF PATCH
    else
        return NULL;
}

My question to you, dear /prog/riders, is whether this is completely pantsu-on-head retarded bullshit or if it'll actually work. I can't compile anything right now, so I'll let you be my interpreter.

BREAKING NEWS!

Turns out the error isn't in the parser at all. It's somewhere else in the code. The plot thickens.

After fumbling about for a while, it turns out that it all comes down to commenting out the following two lines in format_mp3.c:

    //value = util_conv_string (in_value, charset, plugin->charset);
    //if (value == NULL)
        value = strdup (in_value);

The only thing remaining is to add a charset=UTF8 header to websites, but anyone should be able to figure that out.
