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.

derp[a+1]
derp[a+1]
derp[a+1]
derp[a+1]
derp[a+1]
Um... no. Also not all Unicode escapes are 4 chars long.
