rijndael-api-fst.[ch]:
- switch to use new low level rijndael api.
- stop using u8, u16 and u32.
- space cleanup.

Tested by: gbde(8) and phk's test program

- revert to old rijndael code. new rijndael code broke gbde.
- since aes-xcbc-mac and aes-ctr require functions in new
rijndael code, aes-xcbc-mac and aes-ctr are disabled for now.

Fix alignment problem on 64 bit arch.
I only tested if it doesn't break anything on i368. Since I
have no 64 bit machine, I cannot test it, actually.

Fixed AES encryption algorithm bug

PR: kern/38465
Obtained from: Ramana Yarlagadda <ramana.yarlagadda@analog.com>

Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.
