We have been using forget() to prevent auto-reconnection when the user hits back to Wifi setup. This has the side effect of forgetting networks, which is undesirable especially for password protected APs. The new mechanism keeps a flag on whether the user has selected a connection. Only auto-advance if the user has picked a network and there is a valid WiFi connection. The new EXTRA_REQUIRE_USER_SELECTION can specify whether a user selection is required initially. That is, whether to auto finish if the system connected to a network without user input. The default is false so WiFi can be skipped if the user started setup wizard with a valid WiFi connection (e.g. after System Update). Note that a user selection is always required when the user goes back from the next screen. Since the new AP dialog does not have a connect button, the SKIP button in the navigation bar also changes to NEXT when there is a valid WiFi connection, so the user can hit NEXT if they decided not to change the network.
