NDN-CCL

In NDN-CPP branch issue/1921-NDN_MAX_PACKET_SIZE, added static inline method getMaxNdnPacketSize(). Noted that expressInterest with throw an exception if the encoded Interest size exceeds this.

This is blocking on feature #2579 because we need Face.putData so that it will also throw an exception if the encoded Data size exceeds it.

Added the check in putData.
