Log Message:
Add infrastructure to allow ports to override build of in6_cksum.c by
enabling the INET6_MD_CKSUM option, which is defopted into opt_inet.h.
Supply an i386 assembly version of in6_cksum in in_cksum.s; on
P6-family cpu's, this is is roughly 20% faster than the C code in
sys/netinet6 for ethernet-mtu-sized mbufs in L1 cache.  Turn on
INET6_MD_CKSUM in i386/conf/std.i386

While we're here, also nuke some now-obsolete XXX comments from
in_cksum.s.
