refactor(init/data/nat/bitwise): change definitions to avoid WF
...
The type-correctness of binary_rec_eq (the statement, not the proof) depends on unfolding the embedded well-founded definition of mod. This definition avoids it by using two simpler functions bodd and div2 that reduce well in the kernel.

refactor(library/init/data/string/basic): mark string implementation as private
...
See issue #1175
BTW, we may have to revise this decision in the future when we decide to
populate the string library with lemmas.
It is inconvenient to prove the lemmas at string/basic.lean since the
tactic framework has not been defined yet.
Anyway, I think it is worth to keep the private for now, and make sure
nobody relies on its implementation.

refactor(*): wrap string in a structure

We want to make sure string users do not depend on the string
implementation. This is the first step.
We need this refactoring *now* to make sure it will not be
super painful to address issue #1175

fix(library/init/meta/interactive): use replace_target at simp_goal
...
replace_target uses id_locked.
The id_locked solution is more robust because simp may build a proof
using refl lemmas, but type_context may not be able to establish that
the previous and new target are definitionally equal.
@Armael This commit fixes the issue in the KreMLin proof you showed me.
Now, the following tactic succeeds (as expected)
```
simp [lowstar_semantics.apply_ectx],
```
and the resulting goal is
```
...
|- exp.subbuf (exp.loc (b, n, list.nil field)) a_1 = exp.subbuf ↑?m_1 ?m_2
```
