Old description:

> related types). This also involves fixing various bad usages of `mpz_t`
> (it was `ctypedef`'ed as `void*`, meaning you could do with it what you
> wanted and Cython wouldn't complain) and removing many many places where
> a ''pointer'' to an `mpz_t` was passed instead of the `mpz_t` itself.

New description:
Similar to #16583, we should fix the declarations for `mpz_t` (and related
types). This also involves fixing various bad usages of `mpz_t` (it was
`ctypedef`'ed as `void*`, meaning you could do with it what you wanted and
Cython wouldn't complain) and changing many many functions to pass an
`mpz_t` instead of an `mpz_t*` (in particular, NTL functions `mpz_to_ZZ`
and `ZZ_to_mpz`).
