Fcilitate proof of arithmetic on bitvectors by Alt-Ergo
...
Add three new lemmas on addition, subtraction and negation on
bitvectors, that are used by Alt-Ergo. Remove them in the driver
targetting SMTLIBv2.
Also remove upper bound in guard of lemma to_uint_sub_bounded which
is not needed.

remove unsound module null.Null
...
this was unsound for the following reason:
- in WhyML, it is possible to make the difference between Null and (Value Null)
- in OCaml, the two would be the same
fix (and improve) example bag, which was the only use of null.Null so far
