If a network no longer satisfies a NetworkRequest, send the onLost NetworkCallback. If it was a real request (not listen) then update the NetworkFactories. To test this change I created a little infrastructure to fake different Internet connectivity probe results during tests. This allowed me to rewrite some of ConnectivityServiceTest's logic for validating networks. This brought to light a couple issues that I had to address to keep tests passing: 1. testUnlingeringDoesNotValidate was relying on a bad side-effect of my old method of ConnectivityServiceTest's logic for validating networks, so I rewrote the test. 2. ConnectivityService was not sending out NetworkCallbacks for WiFi when Cellular was validated. I'm including a fix for this in this CL also.
