  Modified files:
    sys/netinet          in.c in_var.h 
  Log:
  The IPv4 code should clean up multicast group state when an interface
  goes away. Without this change, it leaks in_multi (and often ether_multi
  state) if many clonable interfaces are created and destroyed in quick
  succession.
  
  The concept of this fix is borrowed from KAME. Detailed information about
  this behaviour, as well as test cases, are available in the PR.
