the same already used e.g. by PyNumber_Check) to all of them.
* Add timezone to datetime C API
* Add documentation for timezone C API macros
* Add dedicated tests for datetime type check macros
* Remove superfluous C API test
* Drop support for TimeZoneType in datetime C API
* Expose UTC singleton to the datetime C API
* Update datetime C-API documentation to include links
* Add reference count information for timezone constructors
PyDateTime_DELTA_GET_DAYS, PyDateTime_DELTA_GET_SECONDS,
PyDateTime_DELTA_GET_MICROSECONDS.
Please use them instead of directly accessing PyDateTime_Delta struct members.
