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)
