Mikolaj Golub 8856400bcb Make ipfw nat init/unint work correctly for VIMAGE: ... * Do per vnet instance cleanup (previously it was only for vnet0 on module unload, and led to libalias leaks and possible panics due to stale pointer dereferences). * Instead of protecting ipfw hooks registering/deregistering by only vnet0 lock (which does not prevent pointers access from another vnets), introduce per vnet ipfw_nat_loaded variable. The variable is set after hooks are registered and unset before they are deregistered. * Devirtualize ifaddr_event_tag as we run only one event handler for all vnets. * It is supposed that ifaddr_change event handler is called in the interface vnet context, so add an assertion.
