Rustls does not offer a documented way to accept valid certificates with
invalid hostnames. Implementation of certificate verification in Rustls
does not have a public API and reimplementing it is error-prone.
A lot of work from @Hocuri and @Simon-Laux mostly.
This exposes the API of the deltachat-provider-overview crate on the
deltachat FFI API, allowing clients to use it to help users set up
their accounts.
