For now, these analyzers are just copies of the legacy HTTP analyzers. But,
during the HTTP refactoring, it will be the main place where it will be
visible. And in legacy analyzers, the macro IS_HTX_STRM is used to know if the
HTX version should be called or not.
Note: the following commits were applied to proto_http.c after this patch
was developed and need to be studied to see if an adaptation to htx
is required :
fd9b68c BUG/MINOR: only mark connections private if NTLM is detected
This file is empty for now. But it will be used to add new versions of the HTTP
analyzers based on the internal representation of HTTP messages (not implemented
yet but called HTX).
