* The net_domain's lock is now a recursive lock.

* Fixed all route locking problems, of which there were numerous
  ({add|remove}_route(), and list_routes() did not lock at all). Added
  lock assertions in functions that don't do the locking themselves.
* A route will now be removed from the list in remove_route(), not in
  put_route_internal(). Before, a route could easily be removed twice, causing
  remove_route() to release references it did not own. This fixes bug #2706.
