Add conversation_new_full and find_conversation_full, which take
arbitrary element lists instead of fixed addresses and ports.
Update the comments in conversation.h to be more Doxygen-conformant.
Update README.dissector.
Use the new functionality to add initial conversation support to the
Falco Bridge dissector.
libsinsp currently only supports string and unsigned 64-bit integer
field types. For string fields that might contain a parseable address,
add ".v4" and ".v6" subtree items with a corresponding field type.
For example, the ct.srcip field now dissects as
Sysdig Event 1: 880 bytes

[Source IP (IPv4): 3.92.225.50]
The extract_fields struct and calling convention changed, so update to
match. Extract all of our fields at once, which noticeably speeds up
dissection here.
Convert our conversation protocols to a dynamic list and add
add_conversation_filter_protocol(). Use it in the Falco Bridge plugin to
add protocols with conversation filters.
Remove unused header definitions in packet-falco-bridge.h and move the
remaining content to packet-falco-bridge.c and conversation-macros.h.
Explicitly set our header files in CMakeLists.txt.
Fix
../plugins/epan/falco_bridge/packet-falco-bridge.c: In function ‘register_conversation_filters_mappings’:
../plugins/epan/falco_bridge/packet-falco-bridge.c:105:1: error: old-style function definition [-Werror=old-style-definition]
register_conversation_filters_mappings()
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Sysdig Bridge plugin loads Falco plugins, so rename it to Falco
Bridge.
Make it optional and dependent on libsinsp+libscap, similar to our codec
plugins.
Remove some unused code.
