Remove mkludge stuffs

For unknown reasons, IPv6 multicast addresses are linked to a first
IPv6 address assigned to an interface. Due to the design, when removing
a first address having multicast addresses, we need to save them to
somewhere and later restore them once a new IPv6 address is activated.
mkludge stuffs support the operations.

This change links multicast addresses to an interface directly and
throws the kludge away.

Note that as usual some obsolete member variables remain for kvm(3)
users. And also sysctl net.inet6.multicast_kludge remains to avoid
breaking old ifmcstat.

TODO: currently ifnet has a list of in6_multi but obviously the list
should be protocol independent. Provide a common structure (if_multi
or something) to handle in6_multi and in_multi together as well as
ifaddr does for in_ifaddr and in6_ifaddr.

Don't give up just because inet6 sysctl knobs aren't available

It can happen normally, for example run a kernel without INET6 or
run a rump_server without librumpnet_netinet6.so.

Use asysctl.

Add a const for the oid list.

Introduce new sysctls for obtaining interface-specific addresses:
- net.sdl for the active link-layer adddress (the MAC)
- net.ether.multicast for the Ethernet multicast addresses
- net.inet6.multica

Introduce new sysctls for obtaining interface-specific addresses:
- net.sdl for the active link-layer adddress (the MAC)
- net.ether.multicast for the Ethernet multicast addresses
- net.inet6.multicast for the IPv6 multicast groups
- net.inet6.multicast_kludge for temporarily removed multicast groups

Use this sysctls for replacing the kmem grovelling in ifmcstat(8).

Inline trivial helper function.

Kill __P. Use static.

Remove !NetBSD code.

netstat(1) and ifmcstat(8): ifnet was renamed to ifnet_list, PR/48850.

use new scopeid functions

Ensure entire sockaddr_dl is obtained. May not have
been the case previously for interfaces with long names.

Fix WARNS=4 issues (-Wextra -Wshadow)

NI_WITHSCOPEID was not picked up by IETF standardization process.

print addresses in extended scoped address notation.

bring in latest KAME tree. show kludge entry.

sync with latest KAME. cleanup on interface type determination.
