    core: fix PropertiesChanged signals for IP-related properties
    
    To present a consistent API to clients, the IP-related properties
    are only valid when the device has finished IP configuration.  But
    they are set before that happens, and their change notifications
    were emitted before the IP configuration was considered valid.
    Re-emit the change notifications when the device enters the IP_CHECK
    state (and thus has IP configuration) and also when the device
    deactivates to enusre clients have up-to-date IP-related property
    information.
    
    For the changes to has_ip_config(), the priv->ipX_state checks are
    not necessary since the device will have valid IP configuration
    when it enters the IP_CHECK state.  The other checks can be
    consolidated into a single statement.
