Hence, I now can use lurette instead of lurette_old in the crazy
rabbit nonreg tests.

Indeed, for some reasons, this lib was useable of ocaml 4.07.0

ocaml
  #use "topfind";;
  #require "rdbg-plugin";;
  #require "lutin";;

Error: Reference to undefined global `Stdlib__bigarray'

(that now have a reset field)

Indeed, otherwise, the compilation fails for ocaml 4.06 >= if it is the system switch.

with lustre-v6 and lutin rdbg-plugins statically linked.

Add rdbg as a submodule, to be able to share files in lurette-nocaml/src/

find where lib are installed (work both on system and custom opam)

I used to patch camlidl and put it in my local opam repo, by that was a terrible idea.

Add a CI pipeline

Basically, I have added the missing fields

I migth change the operator priority later on.

also, add -I/usr/local/include/ in CCOpt oasis rules for packages
that depend on gmp, as darwin can not find headers in this dir
(bouh).  There is probably a better way to turn arouns that, but...
