Task #1205: NDNLP

NDNLP fragmentation and reassembly on Ethernet multicast face

Description

Add fragmentation in Ethernet sending path.
Each EthernetFace needs a single ndnlp::Slicer.

Add reassembly in Ethernet receiving path.
EthernetFace must distinguish the sender address, and create one ndnlp::PartialMessageStore per sender.
If a sender has been idle for some configuration duration, destroy its PartialMessageStore.

Modify link layer byte counters to reflect NDNLP byte counts.
In the receiving path, the byte counter should include all received NDNLP packets, even if a network layer packet could not be reassembled due to a lost fragment.

What's the relationship between ndnlp::Slicer and the face? Should we create a new instance of Slicer for each packet that has to be fragmented, or should there be just one instance, member of EthernetFace, with the same lifetime as the face object?

Technically this feature conflicts with #2222, but I'll wait for this to merge before start implementation of #2222.

Hello Junxiao,
I didn't get you last update since on gerrit you wrote "It needs to go into ndn-cxx. This Change is blocked until then."
Thanks.
