3d4146e21f Add asm versions of blowfish and des transforms for i386. 
This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!

C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart.  Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so.  It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have.  The DES CBC code
doesn't have this problem.

Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.

ad9d3794b0 Implement support for IP/TCP/UDP checksum offloading provided by 
network interfaces.  This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us.  In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software.  This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.

We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.

Note: hardware-assisted checksumming defaults to "off".  It is
enabled with ifconfig(8).  See the manual page for details.

Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.

df9784d749 pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2 (UCB copyrighted). 
have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).

benefit: the follwoing command now works.  previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *.  it was
introduced by 4.3BSD-reno and never corrected.

XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
