description:
this commit contains two sets of unrelated changes:
"while I was here" I checked other KAME implementations for their icmp6.h
version, and thus:
  - added a define for MLDV2_LISTENER_REPORT from FreeBSD
  - added defines for the missing ICMP6_DST_UNREACH codes

then on to what I actually wanted to do:
  - adds strings for the types and codes (encapsulated by ICMP6_STRINGS)
    for the use of npfctl and other tools that might want to parse
    human-friendly names instead of the corresponding number for ipv6-icmp
    types and codes.
    The strings are ordered such that their index is (as far as is practical)
    the number belonging to the name, which is why there are
    icmp6_type_err (use directly) and icmp6_type_info (add 128)
