Subject: Declaremods: major refactoring, stop duplicating libobjects in
 modules

 When refering to a module / module type, or when doing an include,
 we do not duplicate and substitution original libobjects immediatly.
 Instead, we store the module path, plus a substitution. The libobjects
 are retrieved later from this module path and substituted, typically
 during a Require. This allows to vastly decrease vo size (up to 50%
 on some files in the stdlib). More work is done during load (some
 substitutions), but the extra time overhead appears to be negligible.

 Beware: all subst_function operations should now be
 environment-insensitive, since they may be arbitrarily delayed.
 Apparently only subst_arguments_scope had to be adapted.

 A few more remarks:

 - Increased code factorisation between modules and modtypes
 - Many errors and anomaly are now assert
 - One hack : brutal access of inner parts of module types
   (cf handle_missing_substobjs)
