Right, we have to pick one of the two ways where neither is optimal.
I still think I'm going to try with a single CURLOPT_WRITEFUNCTION callback to
start with and a "curl_ws_meta()" function that can be used from within that
callback to get additional data about the frame - when used in frame mode.
I think getting something working that we can try with is a good thing and
then if this turns out feeling too awkward and special, we can switch it
around and do a separate callback option instead.
