1) Mark the following GSL features as deprecated: - gsl::unique_ptr (always) - gsl::shared_ptr (always) - gsl::byte (since c++17) - gsl::joining_thread (never implemented) 2) Refactor existing deprecations to use the new GSL_DEPRECATED(msg) macro. 3) Create a section in the README for deprecated features in the standard.

Why is that macro introduced? It was not needed before. Did some code not compile without this macro?
And why is this macro exported?
A macro with a generic name like BYTE_TYPE looks like it has potential to break existing code.

It worries me if that change is necessary. That would mean that users using GSL might also need to use BYTE_TYPE instead of gsl::byte, which in my opinion is a change for the worse.
