dojailconfig: Do not return a jail config unless the node is really jailed. doifconfig: Look at the node name, and return ifconfig info specific to the name instead of always returning all info for the machine. Upon boot, virtual interfaces will not be setup, but instead will be setup when the jail is setup. When the jail requests ifconfig info, it gets only its list of interfaces to setup. dolinkdelays: Ditto, since linkdelays will be setup after per-jail interfaces are setup.
