It makes no sense to include it in the public API as clients can't make any meaningful use of it via public API, it can only be used if one also includes other internal/private headers that we don't install. It's used only in the testing code, which has access to the internal headers. Fixes #2739, at least to some degree. I decided against moving things to a separate `tox_testing.h` and leaving only things in `tox_private.h` that we are fine with clients using, as otherwise `tox_lock()` / `tox_unlock()` would have to be moved out of `tox_private.h` to somewhere else, but `tox_private.h` actually sounds like the right place for them, naming-wise. So perhaps it's fine if we have things in `tox_private.h` that we don't want clients to use.
