It was due to the event_incr function in MainArg, that is using a
reference to count event numbers, and that was not saved and restored
by LutinRun.

And this counter was used to set the PRGS! which is actually useless
as it is handled in LutinRun via save_state/restore_state now.

It is not clear if my monadisation work was really necessary. In
theory, it is, but not in the examples I've tried. Sigh.

Rationale for removing the fair mode:
 - the code for choosing the mode was ugly
 - it duplicates the effort
 - they other means to be fair (via weigths)
 - it can be very expensive (it breaks the sharing in the bdd, and computing
   polyedron volume is costly). hence it is not in the spirit of all the tradeoffs
   used elsewhere in design choices.
 - I've never used it (well, except in the tuto...)

New: take advantage of options added in rdbg/RdbgWrapper cf sha bacf7677bcb7ceeffa127602204ee8277787ed19

which aims at Adding bddrand, simple front-end to the lutin Random
toss machinary (the log msg was wrong).

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/
