Revision of the FSetWeak Interface, so that it becomes a precise
subtype of the FSet Interface (and idem for FMapWeak / FMap).
1) No eq_dec is officially required in FSetWeakInterface.S.E
(EqualityType instead of DecidableType). But of course,
implementations still needs this eq_dec.
2) elements_3 differs in FSet and FSetWeak (sort vs. nodup). In
FSetWeak we rename it into elements_3w, whereas in FSet we
artificially add elements_3w along to the original elements_3.
Initial steps toward factorization of FSetFacts and FSetWeakFacts,
and so on...
Even if it's not required, FSetWeakList provides a eq_dec on sets,
allowing weak sets of weak sets.
