itojun 74ad87bc53 gif interface now uses generic software interrupt 
(on archs that support it).  also, make gif ALTQ-capable on outgoing.
sync with kame, comments from thorpej.

itojun cad488d032 sync gif interface code with latest kame. 
IFF_RUNNING is clearified.  attach/detach logic is more clearner.
the old code mistakenly set IFF_UP by itself, now the behavior is gone.

itojun 3909133548 introduce sys/netinet/ip_encap.c, to dispatch inbound packets 
to protocol handlers, based on src/dst (for ip proto #4/41).
see comment in ip_encap.c for details of the problem we have.
there are too many protocol specs for ip proto #4/41.
backward compatibility with MROUTING case is now provided in ip_encap.c.

fix ipip to work with gif (using ip_encap.c).  sorry for breakage.

gif now uses ip_encap.c.

introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code
with ip proto #41).
