Issue #25260: Fix ``python -m test --coverage`` on Windows. Remove the list of
ignored directories.

OpenBSD", I'm not sure that the change was really needed. I read the test
result of an old build because the OpenBSD was 100 builds late.

Patch written by Remi Pointel.

Restore also errno value before calling PyErr_SetFromErrno().

* Fix "-m test --forever": replace _test_forever() with self._test_forever()
* Add unit test for --forever
* Add unit test for a failing test
* Fix also some pyflakes warnings in libregrtest

When the -jN command line option is used, display tests running since at least
30 seconds every minute.

No need to support.verbose in Regrtest.run_tests(), it's always set in
runtest().

* Remove runtest_ns(): pass directly ns to runtest().
* Create also Regrtest.rerun_failed_tests() method.
* Inline again Regrtest.run_test(): it's no more justified to have a method

* Rename setup_python() to setup_tests()
* Remove use_resources parameter of runtest()

Slaves (child processes running tests for regrtest -jN) now inherit
--memlimit/-M, --threshold/-t and --nowindows/-n options.

* -M, -t and -n are now supported with -jN
* Factorize code to run tests.
* run_test_in_subprocess() now pass the whole "ns" namespace to the child
  process.

* run_test_in_subprocess() now pass the whole "ns" namespace to the child
  process.

Running the Python test suite with -jN now:

- Display the duration of tests which took longer than 30 seconds
- Display the tests currently running since at least 30 seconds
- Display the tests we are waiting for when the test suite is interrupted

Clenaup also run_test_in_subprocess() code.

Python doesn't display the refcount anymore by default. It only displays it
when -X showrefcount command line option is used, which is not the case here.
regrtest can be run with -X showrefcount, the option is not inherited by child
processes.

Add a new Regrtest.run_test() method to ensure that --coverage pass the same
options to the runtest() function.

Move the code to run tests in multiple processes using threading and subprocess
to a new submodule.

Move also slave_runner() (renamed to run_tests_slave()) and
run_test_in_subprocess() (renamed to run_tests_in_subprocess()) there.

with attributes and methods.

The --threshold command line option is now ignored if the gc module is missing.

* Convert main() variables to Regrtest attributes, document some attributes
* Convert accumulate_result() function to a method
* Create setup_python() function and setup_regrtest() method.
* Import gc at top level
* Move resource.setrlimit() and the code to make the module paths absolute into
  the new setup_python() function. So this code is no more executed when the
  module is imported, only when main() is executed. We have a better control on
  when the setup is done.
* Move textwrap import from printlist() to the top level.
* Some other minor cleanup.
