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.
