BTW, fix iterator handling which was not working from SocExecDbg

To do that, I have created a new dedicated module L2lExpandEnum, that
actually also deals with -eei (which was probably wrong, even if I
have not counter-exemple).

Use 1-hot encoding instead of log-encoding

I've fixed a bug in L2lExpandArrays that occurs on equation such as
  some_bool = (some_array1 = some_array2);

Also, I've rewritten Lv6Compile for more readability

Remove duplicated code when using SocMap.find and co

Also, use rdbg instead of lurettetop to run the test.

BTW, add a missing module (L2lCheckCKeyWord) introduced in the previous change
(necessary for the v6 rdbg plugin)

var_info appears in
- node decl
- left var
- static args

not yet working. I commit as Ive fix a missing dep on WenOnId in the _oasis.

Ditto for Misc and Compile

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