Improved performance on data-fwd node:
- 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.
