This way, the crates can be published without interfering with
potential future non-bindings `nix-` crates, if Nix proper wants to
have native rust code, for instance.
This builds on the previous commit to make it compatible with the
currently locked build configuration.

This spreads out transitively to many places and requires that
we use `check_call!` instead of `check_one_call` in a number of
places.

> I couldn't figure out a way to use () for the function call, but I didn't try that hard.
I (Robert) have also given it a shot, briefly, unsuccessfully.
While I was critical of over-engineering this, it turns out that
when we start to use `mut`, a macro is much more practical, because
it doesn't create a new scope where we need a copy of a mutable
reference, which of course is not allowed.

The mutation-based methods had some pitfalls, and we don't really
need them.
We could re-add them if we need to.

This makes it easier to stick to a regular pattern and not forget
to check the context afterwards.
