Fix handling of scoped IPv6 addresses in IPSec code.

* in ipsec_encap() embed scope zone ids into link-local addresses
  in the new IPv6 header, this helps ip6_output() disambiguate the
  scope;
* teach key_ismyaddr6() use in6_localip(). in6_localip() is less
  strict than key_sockaddrcmp(). It doesn't compare all fileds of
  struct sockaddr_in6, but it is faster and it should be safe,
  because all SA's data was checked for correctness. Also, since
  IPv6 link-local addresses in the &V_in6_ifaddrhead are stored in
  kernel-internal form, we need to embed scope zone id from SA into
  the address before calling in6_localip.
* in ipsec_common_input() take scope zone id embedded in the address
  and use it to initialize sin6_scope_id, then use this sockaddr
  structure to lookup SA, because we keep addresses in the SADB without
  embedded scope zone id.
