Aaron Hill b36fdc46db Remove several usages of 'unsafe' (#968)
* Replace UnsafeCell in DateServiceInner with Cell

The previous API was extremely dangerous - calling `get_ref()`
followed by `reset()` would trigger instant UB, without requiring
any `unsafe` blocks in the caller.

By making DateInner `Copy`, we can use a normal `Cell` instead
of an `UnsafeCell`. This makes it impossible to cause UB (or even panic)
with the API.

* Split unsafe block HttpServiceHandlerResponse

Also add explanation of the safety of the usage of `unsafe`

* Replace UnsafeCell with RefCell in PayloadRef

This ensures that a mistake in the usage of 'get_mut' will cause
a panic, not undefined behavior.
