* Reworked the complete stack to allow more than one address per network

interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
  complete, though, InterfaceAddresses need to hold references to their
  interface as well).
* There are two known regressions of this commit that I will fix later:
  - you cannot remove interfaces anymore
  - IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
  not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
  the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
  is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
  set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
  available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
  anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
  belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.
