Change the behaviour of tun(4) on close.
- if the interface was auto-created by opening a /dev/tun* device it will
auto-destroy on close. This is comparable to ifconfig tun0 destroy and
will remove all routes and addresses associated with the interface.
- if the interface was created by ifconfig(8) or hostname.if(5) the interface
is persistent -- it is just marked as not running. Especially routes are no
longer removed when the interface is closed. This is useful for static
setups like the server side of a ssh vpn or static qemu session.
This behaviour is more logic then the half done cleanup that is currently done.
