--- IPv6Route: NF const was changed, other lost changes when moved IPv6Route to a new file
module tests: fixed routingFile parameters
----fixed RoutingTableRecorder for Omnetpp master, too
----SCTP fixes: was unspecified address problems

the new Address class can store more different unspecified addresses
the sctp code creates different unspecified addresses
IPv4: implemented netfilter, ported MANET protocols to use it

- IPv4.cc/h no longer has #ifdef WITH_MANET
- INetfilter added, good for all network layer protocols
InternetCloud: refactoring for ARP and INetFilter

connections between ARP and IPv4 was changed, IPv4 now not send all msg to ARP.
delayer registered as a netfilter hook to IPv4
----InternetCloud: fingerprint changed
InternetCloud: ChangeLog
Turn off IPv6 routing by default.
introducing routingTableModuleName parameter -- TODO half-cooked!

- attempt is to get rid of the *Access classes, this time only for routing tables
- parameter name should rather be routingTableModule
- problem is e.g. IPv4AddressConfigurer -- how should it know where to find routing tables of hosts??
----routingTableModuleName parameter setting was missed in NodeBase6
Address: new address types: MACAddress, ModuleIdAddress, ModulePathAddress; added GenericNetworkProtocol & co.
---- GenericNetworkProtocol: bugfix: nextHop vs nexthop, *iter was erased before used the iter->nextHop
Address: Implemented efficient address.

Also:
- Added check to prevent accidentally turning an IPv6 address into something else.
- Added check for NONE address type in conversion functions.
- Added some inline declarations.
--- Address: str() was duplicated
added MultiNetworkLayer
Record all routing table changes.
IPv6, tunneling: bugfix: was mixed usage of interface ID and interface index

added a new getBiggestInterfaceId() for IInterfaceTable --> NOT A GOOD IDEA
IPv6 - netfilter - not completed, untested
Renamed routingTableModule parameter to routingTable; networkProtocolModule ditto
