netinet/netinet6: Add necessary includes to make these standalone.

CTASSERT -> __CTASSERT to unbreak userland build.

While here move __packed in tcp_debug.h back to where it was and
note removal warrants more investigation.

Sprinkle CTASSERT to enforce on-wire layout without __packed

Remove __packed from various network structures

They are already network aligned and adding the __packed attribute
just causes needless compiler warnings about accssing members of packed
objects.

ip6: Remove __packed attribute from ip6 structures

They should naturally align.
Add compile time assertations to ip6_input.c to prove this.

branches: 1.25.6;
IP6_EXTHDR_GET performs a basic mbuf operation, which has nothing to do
with IPv6. So declare an IP-independent M_REGION_GET, and make
IP6_EXTHDR_GET an alias to it.

Remove IP6_EXTHDR_GET0, remove pointless XXXs, and style.

branches: 1.23.2; 1.23.90; 1.23.96;
Convert many of the uses of __attribute__ to equivalent
__packed, __unused and __dead macros from cdefs.h

branches: 1.22.16; 1.22.22; 1.22.24; 1.22.28;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.21.14;
Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292).
* RFC 3542 isn't binary compatible with RFC 2292.
* RFC 2292 support is on by default but can be disabled.
* update ping6, telnet and traceroute6 to the new API.

it was not possible to use cvsmove in this case.
