// 1. A network connection becoming available or going away. For example
// plugging or unplugging an Ethernet cable, WiFi or cellular modem
// connecting or disconnecting from a network, or a VPN tunnel being
// established or taken down.
// 2. An active network connection's IP address changes.
// 3. A change to the local IP routing tables.
// The signal is produced when the change is complete. For example if a new
// network connection has become available, the signal is issued after OS has
// finished establishing the connection (i.e. DHCP is done) to the point where
// the new connection is usable. |type| indicates the type of the active
// primary network connection after the change. OnNetworkChanged will always
// be called with CONNECTION_NONE immediately prior to being called with an
// online state.
