Yes, it would be nice to have just one callback for all WS modes (RAW,
FRAME, MESSAGE) but using CURLOPT_WRITEFUNCTION callback for that purpose
doesn't seem like an optimal solution to me because of the problems related
to passing curl handle to it and making a function call to get WS context
metadata.
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.
