many services depend on other services that bring up network interfaces. Examples are ipv6 tunneling clients or VPNs. As there are multiple choices for these network-interface-providing services, it's not nice to hardcore these deps in every service. This change sets up a generic config option for this purpose. providers (gw6c/gogoclient/openvpn) can plug into this to signal they bring up an important interface. Daemons that need these interfaces, can then depend on the 'all-interfaces' event, instead of the individual services. By default, the event fires when network-interfaces completes. svn path=/nixos/trunk/; revision=32764
