expanding netinet/icmp6.h with strings (et al)

["S.P.Zeidler" <spz%serpens.de@localhost>]

Hi,

the following patch:
- adds a define for MLDV2_LISTENER_REPORT from FreeBSD (the name is as
  good as any and if it's there, the names won't grow apart as easily)
- adds defines for the missing ICMP6_DST_UNREACH codes
- adds strings for the types and codes (encapsulated by ICMP6_STRINGS)

Comments? Cries of pain? Shedding of bikes? ;)
