Fixed non-determinism.
v3.058

 - Added new attribute 'routing=dynamic'.
   This should be used at interface level. It has the same effect as
   'routing=manual', but the new name shows more clearly, that the
   route isn't configured manually but by some routing protocol.
 - Attribute 'routing=manual' has been restricted.
   It is no longer allowed as attribute of interface, but still at
   router. The restriction of 'routing=manual' must be enabled by new
   config option 'check_routing_manual'. This option will be removed in
   the next but one release and the check will be fully enabled then.
 - Added new attribute 'extend_unbounded' at owner.
   Until now, check for inconsistent extended owners was disabled
   globally by default. This check should now be enabled with
   --check_owner_extend=1. For individual owners, the check can be
   disabled again using attribute 'extend_unbounded'. Check has been
   improved and a test case was added. Config option
   'check_owner_extend' will be removed in the next but one release
   and the check will be enabled by default.
 - Check for validity of attribute 'show_all' of owner has been fixed.
 - Better error message for ID host with IP range that is not a subnet.
