* NS_BINDING_SUCCEEDED: link is valid
* NS_BINDING_FAILED: link is invalid (gave an error)
* NS_BINDING_ABORTED: timed out, or cancelled

* call aObserver.OnStartRequest followed immediately by
* aObserver.OnStopRequest. It is recommended that the caller use
* OnStopRequest to act on the link's status. The underlying request
* will not be cancelled until after OnStopRequest has been called.
* @param aContext
* A closure that will be passed back to the nsIRequestObserver
* methods.
