Implement request #18662: Unable to configure SSL settings.

OpenID_RelyingParty now has a setRequestOptions() method that can be
used to configure all HTTP_Request2 objects that are used to fetch
data via HTTP.

Specifying curl as adapter and modifying the SSL settings is now possible
at a central place.
