Announce all interfaces to devd on attach/detach. This adds a new devctl

Browse Source 
notification so all interfaces including pseudo are reported. When netif
creates the clones at startup devctl_disable has not been turned off yet so the
interfaces will not be initialised twice, enforce this by adding an explicit
order between rc.d/netif and rc.d/devd.

This change allows actions to taken in userland when an interface is cloned
and the pseudo interface will be automatically configured if a ifconfig_<int>=""
line exists in rc.conf.
