Changes in the new implementation are:
- the adjacency index is replaced with a dpo that allows the single face node
to dispatch the packet to the right vlib node.
- local and remote address in the face are replaced with a single nat address
which is used to perform the nat operation when rewriting an interest or a
data (in case of tunnels the nat address will be equal to 0)
- the list of next hop in the load balance is no longer a list of dpos but
a list of face id (this makes the code easier and increases the number of
next hop we supports)

Added two new messages in the binary api:
- hicn_api_face_cons_del to delete a consumer face
- hicn_api_face_prod_del to delete a producer face
Added the corresponding commands in the vpp_api_test for debugging and testing
Reworked the cache policy structure to add a new function that flash the content store
from the content coming from the destroyed producer face. This is required since the CS
while each producer face has its own lru list. Removing only the producer face without
flushing the CS from the content coming from the producer face will lead to a segfault
in case there is a hit in the CS as the lru no longer exists and it won't be possible
to update the head of the lru.

and we follow the new adjacency. The adj in the face is updated accordingly.

- 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.

- Removed full pit entry initialization in favor of a lighter initialization on few fields
- Squeezed pit entry size in order to store only the number of incomplete faces (as set in HICN_PARAM_PIT_ENTRY_PHOPS_MAX). The bitmap size is now determined by HICN_PARAM_FACES_MAX and optimized to do a fast lookup
Replaced the field is_appface with the field flags in the hicn_buffer_t:
- is_appface is now a flag with value 0x01 (HICN_BUFFER_FLAGS_FACE_IS_APP)
- Added flag HICN_BUFFER_FLAGS_PKT_LESS_TWO_CL (0x02) to handle the copy of pkt with length < than 2*CACHE_LINES (in this case cloning is prevented by the cloning function in vpp). Such flag is initialized by the incoming face of the pkt.
