• Add -W flag support for network column in intpr() (-i flag) and routepr() (-r flag). It is too narrow to show an IPv6 prefix in most cases.

• Accept "local" as a synonym of "unix" in protocol family name.

• Show a prefix length in CIDR notation when name resolution failed in netname().

• Make routename() and netname() AF-independent and remove unnecessary typecasting from struct sockaddr.

• Use getnameinfo(3) to format L2 addr in intpr().

• Fix a bug which showed "Address" when -A flag is specfied in pr_rthdr().

• Replace cryptic GETSA() macro with SA_SIZE().

• Fix declarations shadowing local variables with the same names.

• Add more static, remove unused header files and variables.
