does a KASSERT that the group address is multicast, so the
check if this is indeed true and eventually return a EINVAL if not,
should be done before calling inp_lookup_mcast_ifp. This fixes a kernel
crash when calling setsockopt (sock, IPPROTO_IP, IP_ADD_MEMBERSHIP,...)
with invalid group address.

never been inserted into the pfs_vncache list. Since pfs_vncache_free()
does not anticipate this case, it decrements pfs_vncache_entries
unconditionally; if the vnode was not in the list, pfs_vncache_entries
will no longer reflect the actual number of list entries. This may cause
size of the cache to exceed the configured maximum. It may also trigger
a panic during module unload or system shutdown.
Do not decrement pfs_vncache_entries for the vnode that was not in the
list.

Now that pty(4) is a loadable kernel module, I'd better move /dev/ptmx
in there as well. This means that pty(4) now provides almost all
pseudo-terminal compatibility code. This means it's very easy to test
whether applications use the proper library interfaces when allocating
pseudo-terminals (namely posix_openpt and openpty).

scenario where an anycast address is assigned on one interface,
and a global address with the same scope is assigned on another
interface. In other words, the interface owns the anycast
address has only the link-local address as one other address.
Without this patch, "ping6" the anycast address from another
station will observe the source address of the returned ICMP6
echo reply has the link-local address, not the global address
that exists on the other interface in the same node.

- Interface link-local address is not reachable within the
node that owns the interface, this is due to the mismatch
in address scope as the result of the installed interface
address loopback route. Therefore for each interface
address loopback route, the rt_gateway field (of AF_LINK
type) will be used to track which interface a given
address belongs to. This will aid the address source to
use the proper interface for address scope/zone validation.
- The loopback address is not reachable. The root cause is
the same as the above.
- Empty nd6 entries are created for the IPv6 loopback addresses
only for validation reason. Doing so will eliminate as much
of the special case (loopback addresses) handling code
as possible, however, these empty nd6 entries should not
be returned to the userland applications such as the
"ndp" command.
Since both of the above issues contain common files, these
files are committed together.
