bpo-43913: Fix bugs in cleaning up classes and modules in unittest. (GH-28006)
* Functions registered with addModuleCleanup() were not called unless
the user defines tearDownModule() in their test module.
* Functions registered with addClassCleanup() were not called if
tearDownClass is set to None.
* Buffering in TestResult did not work with functions registered
with addClassCleanup() and addModuleCleanup().
* Errors in functions registered with addClassCleanup() and
addModuleCleanup() were not handled correctly in buffered and
debug modes.
* Errors in setUpModule() and functions registered with
addModuleCleanup() were reported in wrong order.
* And several lesser bugs.
(cherry picked from commit 08d9e597c8ef5a2b26375ac954fdf224f5d82c3c)
