- 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"

To run it, just launch just:

  cd test/
  make test.kcg

(which breaks lurettetop)

nb : Mamadou's change broke some tests (18->53). Empty body is
generated for nodes that have one eq.  I'll fix that later.

-kcg: forces the -esa(expand_arrays) option so that arrays walk with diese.We will see later how to treat properly the arrays.

-kcg: evaluates types enum and struct correctly.
-kcg: evaluates const correctly.

lus2lic -h shows the basic options
lus2lic -more shows more experimental options
lus2lic -dev shows experimental/internal  options

+ the utils/lustrequiv script that tries to state that 2 nodes a equivalent or not
using lesar and lurette.

Indeed, I've missed that case and have no nonreg test for -2ch

that I should have catched then. Sigh.

only affect array concat

by grouping instances of the same type into arrays.

The rationale is to be able to generate for loops with iterators.

The previous code was working, but probably by chance.

Actually, that was the default behavior. Now the default behavior is
to generate loops for iterators.

nb : with -2ch, loops are still always inlined
