  1. Add as_slice and as_mut_slice to Option 

    Extracts an immutable or mutable slice from an option such that, if
the option is a None value, the slice is empty, and if the option
is a Some value, the slice is length one.

The slice is, for all practical purposes except extracting a
pointer, a reference to the actual contents of the owned option. If
it's a Some value, slice index zero contains the contents of the
owned option. If it's a None value, the slice is length zero and
cannot be read from or written to.
