management: ensure Element::Error inherits from tlv::Error
Add static asserts to ensure ndn::nfd::*::Error are subclasses of tlv::Error.
Add WireEncodable and WireDecodable concept checks to
ndn::nfd::* classes that represent TLV abstraction.
Move definition of ChannelStatus, FibEntry, ForwarderStatus,
StrategyChoice methods into .cpp.
Move declaration of FaceScope, FacePersistency, LinkType
into encoding/nfd-constants.hpp.
Eliminate duplicate RibFlags declaration.
