Add a net::HttpNetworkDelegate and a ChromeNetworkDelegate.

net::HttpNetworkDelegate is an interface for providing hooks into http network activity.  ChromeNetworkDelgate implements this interface in chrome/ code.  In the future, it might also implement other interfaces.  My only current intended consumer for this would be extensions.  There's no actual behavior change, this is all just plumbing for now.
