Refactor in_cksum/in4_cksum/in6_cksum implementations:
...
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.
This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

When not compiling for the kernel, use stdio.h instead of sys/systm.h
...
(printf) and locally define the protoype. Makes it possible to use
in_cksum.c for regression testing.

Anyone seriously interested in implementing in_cksum on a new platform
...
should read RFC 1071, so point them to it.
