Add "Basic Usage" to int min_value and max_value docs

This adds "Basic Usage:" to the docs of `min_value` and `max_value`, which makes it consistent with docs of other integer methods.

Convert warning about `*const _` to a future-compat lint

#46664 was merged before I could convert the soft warning about method lookup on `*const _` into a future-compatibility lint. This PR makes that change.

fixes #46837
tracking issue for the future-compatibility lint: #46906

docs: do not call integer overflows as underflows

In the API docs, integer overflow is sometimes called underflow. Underflow is really when the magnitude of a floating-point number is too small so the number underflows to subnormal or zero. With integers it is always overflow, even if the expected result is less than the minimum number that can be represented.

Make fmt::DebugList and friends forward formatting parameters

For example, formatting slice of integers with `{:04?}` should zero-pad each integer.

This also affects every use of `#[derive(Debug)]`.

Move PhantomData<T> from Shared<T> to users of both Shared and #[may_dangle]

After discussing https://github.com/rust-lang/rust/issues/27730#issuecomment-316432083 today with @pnkfelix and @Gankro, we concluded that it’s ok for drop checking not to be much smarter than the current `#[may_dangle]` design which requires an explicit unsafe opt-in.
