I was re-implementing an inneficient topological sort there (using a
linear list instead of logarithmic map). I win 1s on tri.ec (~8000
locals).

I did a map instead of a fold when checking for the absence of cycle.
On programs with 10 000 of equations, I go from 150s to 5s.

Also, force a workflow (via a lock file named commited) that make
sure that the content of lv6version.ml is always correct xrt shat and
git commit number.

as an opam package in the verimag opam repo.

Ditto for Misc and Compile

Also, do not set the seed when comparing compilers.

The objective is touse rdbg instead of lurettetop to perform compiler
comparisons. I will plug it later (cf test/site.exp)

- add a sectiuon on operators priority
- fix the automatic latex grammar generator (now calles yacc2latex)

also force the -rif in the utils/luciole-rif script when used with
lutin or lus2lic.

Indeed, otherwise, in some cases, rdbg or lurette migth not realise
that lus2lic exited in error.

Fix the bug detected in the previous commit where type instance were not propagated in package obtained from a model instance.

More precisely, issuing an "exit 2" is not enough for the
should_work proc in test/site.exp to state that the test fails.

That fix revealed a certain number of bad programs.
Some were not really wrong ; there were just not respecting the
naming convention used to automated the test (i.e., main node name =
file name).

It also releaved a real bug due to the fact that type
instanciatiation is not propagated during model instanciatiation,
where creates a loop between (Lic2soc.process_node and
Lic2soc.soc_of_node). Indeed it searches in the soc the table for an
abstract profile.

* la syntaxe est changee pour l'accepter
* la stucture IdSolver (compil "lazy") contient maintenant
  "all_srcs" qui permet d'acceder si besoin a n'importe quelle info source,
  notamment les params statiques des noeuds identifies par "Pack::name"
