v6.073

 - Added support for dual stack objects, having both, IPv4 and IPv6 addresses.
   This simplifies the modeling of a dual stack toplology.
   It is no longer neccessary to model a separate IPv4 and IPv6 topology.
   Rules between dual stack objects will generate ACls for IPv4 and IPv6.
   Rules between dual stack object and pure IPv4 object will silently ignore
   IPv6 address and generate only ACL for IPv4.
   New attributes have been introduced to define dual stack objects:
   - 'ip6' at network, host, interface and aggregate.
   - 'range6' at host.
   - 'unnumbered6' at network and interface.
   - 'negotiated6' at interface.
   Other changes resulting from use of dual stack objects:
   - If dual stack objects are used as border or inclusive border of an area,
     this defines two areas with identical name:
     one in IPv4 topology and one in IPv6 topology.
   - If dual stack objects are used as interfaces of an pathrestriction,
     this also defines two pathrestrictions in IPv4 and IPv6 topology.
     If the second pathrestriction has only one interface or only interfaces
     outside of a loop, it is silently ignored.
   - New attributes 'ipv4_only' and 'ipv6_only' may be used at service or area.
     This will enable only IPv4 or IPv6 part of dual stack objects.
   - The following attributes are applied only to IPv4 part
     if used in dual stack objects:
     'nat', 'bind_nat', 'subnet_of, 'hub', 'spoke'.
   - Command 'export-netspoc' has been changed to show IPv6 address of
     dual stack objects in attribute 'ip6'.
 - Added new attribute 'auto_ipv6_hosts' to automatically generate
   dual stack hosts from pure IPv4 hosts.
   It will generate IPv6 addresses for hosts
   by combining its IPv4 adress with the IPv6 address of its network.
   These attribute values are provided:
   - auto_ipv6_hosts = readable
     network: ip6 = 2001:db8:1:1::/64;
     hosts: ip = 172.17.1.48;
     ==> 2001:db8:1:1:172:17:1:48
   - auto_ipv6_hosts = binary
     network: ip6 = 2001:db8:1:1::/64;
     hosts: ip = 172.17.1.48;
     ==> 2001:db8:1:1::ac11:130
   - auto_ipv6_hosts = none
     No IPv6 address is generated
   This attribute can be used at network, area and host.
 - Fixed command 'cut-netspoc':
   Full path to management_instance is marked now.
