Description
ndn::lp::Packet throws exceptions of type std::out_of_range and std::length_error to indicate logic errors.
However, NFD's GenericLinkService::doReceivePacket() performs insufficient validation before calling get<lp::FragmentField>(), which may cause NFD to crash when receiving malformed packets.

Subclasses of std::logic_error thrown by lp::Packet are not packet parsing errors. They are logic errors, and it's intentional that these are not derived from tlv::Error.
GenericLinkService should not allow logic errors to escape to its caller.

Feel free to move this to NFD then.

Raising priority since the bug can cause the forwarder to crash on malformed packets.
