This is a short-term workaround. whenever new ipfilter comes out with
proper non-IPv4 support, we should migrate to the new ipfilter.
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.
- 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).
the code is basically from sys/netinet6/in6.c (jinmei@kame).

Without this, if a v6 address is placed before a v4 address in if_addrlist,
a PRU_PURGEIF request for v6 tcp protocol purges also v4 addresses and,
as a result, if_detach fails to request PRU_PURGEIF for v4 protocols
other than tcp.
if there's no rnd(4), random(9) will be used with one-time warning printf(9).

Provide prototypes and implementations for mips_cp0_cause_write,
mips_cp0_status_read, and mips_cp0_status_write. (Writing can, of
course, be quite dangerous.)
with a MIPS4 option at this point -- all the code except for one single
spot is conditionalized with MIPS3. So, don't even pretend about
MIPS4 for now, until it all gets cleaned up.
