core: ip addr - use POSIX INET6_ADDRSTRLEN and INET_ADDRSTRLEN to define sizes

- set the values of IP4_MAX_STR_SIZE and IP6_MAX_STR_SIZE based on them, if defined, or to 15 and 45 - cope with IPv6 with IPv4 tunneling representation (RFC 4291 section 2.2) - cover the requirements of using inet_ntop() - GH #2823

(cherry picked from commit 22a72f3a7725d56f00e22bdc52d44bd53da7c091)
