When NM quits, we don't want to unmanage a device that has an active connection and can take that connection over again when NM starts back up. This makes '/etc/init.d/NetworkManager restart' work seamlessly. All other devices get unmanaged so their connection (and any dependent VPN connections or wpa_supplicant processes) get terminated. This bug caused active VPN connections over wifi to be left running even when they didn't have IP connectivity. There were two bugs: 1) the NMDevice class implemented connection_match_config() for all device subclasses, but only Ethernet devices can assume connections at startup. Thus the quit-time check passed for active wifi devices too, and they weren't properly cleaned up 2) The logic for figuring out which devices to clean up after when quitting was somewhat flawed; we want to default to unmanaging devices and then skip that step for ones that meet specific criteria. Instead the code defaulted to leaving all devices active at shutdown.
