feat: Due to the deep modifications related to names and packet format,
this task cover a large part of the codebase and involves several changes: - the library provides a name data structure (hicn_name_t ), which is composed of a name prefix (hicn_name_prefix_t) and a name suffix (hicn_name_suffix_t), and it has been extended to provide all support functions required for name manipulation, including common prefix computation, as required for the Longest Prefix Match (LPM)in the forwarder, in addition to Exact Prefix Match (EPM). - all code has been rewritten to use this data structure instead of having for instance the forwarder define its own name class (used to be Name and NameBitVector) the code has been refactored to minimize name allocations and copies, one remaining aspect is the difference of name storage between PIT and CS entries (respectively in the PIT entry, and in the message buffer), which causes the packet cache index to be updated when a PIT entry is converted into a CS entry. By storing the name in the PIT/CS entry everytime, we might save on this operation). - hicn-light FIB has been rewritten : code has been refactored and should now be shorter and documented; unit tests have been drafted but more would be required to cover all cases and match the algorithms to add/remove nodes, as specified in the doc. all protocol details and hICN header formats are now abstracted by the library for the forwarder (and thus header.h and  protocols/*.h have been removed from public includes, and replaced by packet.h providing protocol agnostic packet level functions, completely replacing the compat.h header that used to provide similar functions. - this works by exposing a opaque buffer to the application (a kind of socket buffer) which is used by the lib to cache the packet format and offsets of the different layers in the buffer and provider efficient operations (the packet format is either defined for packet construction, or guessed at ingress, and this structure is updated accordingly only once).

+ * @brief Implementation of the compatibility layer.
+ *
+ * The structure of the core API has evolved to support operations of a variety
+ * of packet formats in addition to IPv4/TCP and IPv6/TCP, namely with the use
+ * of ICMP for signalization and AH headers for integrity. The new API format
+ * has been designed to scale better with the multiplicity of packet formats,
+ * and provide a unified interface on top. We maintain an interface for the
+ * former API in this file, which mainly acts as a wrapper on top of new calls.
