[issue47132] Move tests from setobject.c to _testcapimodule

[Oleg Iarygin]

New submission from Oleg Iarygin <oleg at arhadthedev.net>:

Currently, tests for PySet/PyFrozenSet C API are defined in Objects/setobject.c and available via set.test_c_api().

Moving them to, for example, _testcapimodule gives the following advantanges:

- an internal, CPython-specific method stops being available in a public interface of the set class

- CPython already has tests grouped into dedicated packages

- the target package undefines NDEBUG thus making asserts available in release builds

- a user may choose to omit the tests from a build not carrying them around

- a file of 2.5k lines of codes becomes 152 lines smaller.
