Improve address parsing/printing and support scoped addresses.
1. Add a parse_addr function that parses an IP address. This
simplifies the code and also supports scoped addresses.
2. Make prettyprint_addr use getnameinfo instead of inet_ntop
so it can support scoped addresses.
3. Modify the IPv6 address enumeration code to set the scope ID
only if the address is link-local, since scope IDs are only
meaningful for link-local addresses Also, we do not want to
think that two addresses are different if they differ only
in scope ID, because the kernel will treat them as if they are
the same.
4. Modify the address equality checks in sockaddr_isequal and
iface_check to check the scope ID as well.
