mod_echo broken

[David Reid <dr...@jetnet.co.uk>]

mod_echo still uses ap_bread, ap_bwrite and ap_bflush...

    for( ; ; )
        {
        apr_ssize_t r, w;
        (void) ap_bread(c->client,buf,sizeof buf,&r);
        if(r <= 0)
            break;
        (void) ap_bwrite(c->client,buf,r, &w);
        if(w != r)
            break;
        ap_bflush(c->client);
        }
