Bjoern A. Zeeb c179937b98 libc/getnameinfo: stop adding NI_NUMERICHOST where inappropriate ... Checking the first nibble of the IPv6 address to be 0 and then excluding two well known cases (v4-mapped, loopback) leaves us with more cases where the first nibble could be 0, e.g., the RFC 6052, 2.1 Well-Known Prefix 64:ff9b::/96. It is not practical to track them all and it is not clear what lead to this special casing originally, so remove them. While here also remove the IN6_IS_ADDR_LINKLOCAL() + NI_NUMERICHOST case as link-local address resolution does exist. We do leave the IN6_IS_ADDR_MULTICAST() case for now as I could not find any references to any official reverse lookups for these. Adding comments for more case (and some historic behaviour) in order to make it easier to follow the logic.
