Feature #2440

Current spec defines that Data packets without FreshnessPeriod are considered always fresh ("data packet cannot be marked stale", http://named-data.net/doc/ndn-tlv/data.html#freshnessperiod).
I feel that this is not correct and we should change the spec to treat data packets without FreshnessPeriod as never fresh (always stale).
The reason I'm having this feeling is that a single data packet without FreshnessPeriod specified can break protocols that rely on FreshnessPeriod to get "fresh data".
Similar thing can happen when someone specified large FreshnessPeriod, FreshnesPeriod, but we can think about such issue later (e.g., what should be the limit on such freshness).
