[HICN-71]

- Handling the case in which a pushed data hit an existing pit entry (created after the data has gone through the data_pcslookup_node). In this case the data packet is forwarded to the data_fwd_node
- Handling the case in which the hash table (in pcs) is full and it is not possible to allocate another bucket. In this case the packet is dropped.
- Copying packets whose length is less than 128B. VPP prevents to create a chain of vlib_buffer where the first, or middle, vlib_buffer are holding less then 128B.

[HICN-72]
- Assign a /128 subnet to the producer app face.
