Refactor of NetworkDelegate.

* Renames HttpNetworkDelegate to NetworkDelegate, moves to net/base/network_delegate.h. NOTE: this is a layering violation. wtc/eroman/willchan have agreed to this exception because the other solutions are less palatable.
* Move the virtuals in NetworkDelegate to the private section. Use non-virtual public interface as the network stack's interface for notifying the delegate. Add sanity checking to the implmentation in NetworkDelegate. The private virtual interface is for consumers to receive notifications.
* Remove ExtensionIOEventRouter from ChromeURLRequestContext, it is only used by the ChromeNetworkDelegate. Pass it directly to the ChromeNetworkDelegate's constructor.
* Introduce a SystemNetworkDelegate. It does nothing right now.
