v19 gets us a bit closer by adding a missed import for Windows. I've
also removed iddawc support, so the client patch is lighter.

In addition to this question, I'm starting to notice intermittent
failures of the form

    error: ... failed to fetch OpenID discovery document: failed to
queue HTTP request

This corresponds to a TODO in the libcurl implementation -- if the
initial call to curl_multi_socket_action() reports that no handles are
running, I treated that as an error. But it looks like it's possible
for libcurl to finish a request synchronously if the remote responds
quickly enough, so that needs to change.
