Log Message:
Pullup 1.41 [enami]:
- Keep track of allhost multicast address record we joined into
  each in_ifaddr and delete it when an address is purged.
- Don't simply try to delete a multicast address record listed in the
  ia_multiaddrs.  It results a dangling pointer.  Let who holds a
  reference to it to delete it.

Also 1.40 [itojun, req by enami]:
implement multicast kludge table for IPv4.
- when all the interface address is removed from an interface, and there's
  multicast groups still left joined, keep it in kludge table.
- when an interface address is added again, recover multicast groups from
  kludge table.
this will avoid problem with dangling in_ifaddr on pcmcia card removal,
due to the link from multicast group info (in_multi).
