Log Message:
Correctly handle the padding for IPv6-AH, as specified by RFC4302. Seen in
a FreeBSD bug report, by Jason Mader.
The RFC specifies that under IPv6 the complete AH header must be 64bit-
aligned, and under IPv4 32bit-aligned. That's a rule we've never respected.
The other BSDs and MacOS never have either.
So respect it now.
This makes it possible to set up IPv6-AH between Linux and NetBSD, and also
probably between Windows and NetBSD.
Until now all the tests I made were between two *BSD hosts, and everything
worked "correctly" since both hosts were speaking the same non-standard
AHv6, so they could understand each other.
Tested with Fedora<->NetBSD, hmac-sha2-384.
