http-client should support SSL mutual authentication

[rsenior]

The openssl egg supports mutual authentication, but http-client currently does not allow users to specify the openssl connection settings.

Attached two patches that I used to add this new feature to http-client/intarweb

Thanks for reporting this missing feature, and suggesting a fix. The fix looks alright, but I don't think the change in intarweb is required: connection management is something unique to the application. intarweb's responsibility is dealing with the protocol only (parsing headers, wrapping ports to support chunking and so on), so this change does not belong there.

Instead, I have simply added yet another parameter to http-client, which can be overriden in an application that wishes to manage connections. I'm not 100% happy with it yet (because the connection cache is not under application control, only the setting up of connections), but it will have to do for now.

I have committed changeset [32633] to fix this. Please give it a try. It hasn't been released yet, so you'll have to check out http-client trunk. You can use it by supplying a parameter called server-connector, which holds a procedure of 2 arguments: the uri and the proxy (which may be #f if no proxy is in use). The default connector is named default-server-connector, so you can still call this if you want to.

Please let me know how it works for you. If it's all good I will document and release this.
