Don't track a cb-per-POST and remove the PurpleHTTPResponse structure.

The only callback ever used is http_received_cb and the ordering of
responses from the server is not guaranteed to match the order of our requests,
so the metaphor of matching them doesn't make sense. Instead of that, just
track the number of requests (to ensure there is always a request outstanding).

Additionally, pass the data const-ified instead of copying it. It's just
fed to an XML parser anyway.

UPDATE:

Tobias pointed out my explanation was flat-out wrong. The server's replies *do*
correspond to a specific request (HTTP pipelining). I believe what I meant to
say is that the XML in the replies isn't guaranteed to correspond to the
request's payload.

In any event, the critical point is that the callback is always the same, so
there's no need to store it per-request.
