* 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
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.
* test all available ways to run the Python test suite
* test many regrtest options: --slow, --coverage, -r, -u, etc.
Note: python -m test --coverage doesn't work on Windows.
Start to split regrtest.py into smaller parts with the creation of
Lib/test/libregrtest/cmdline.py: code to handle the command line, especially
parsing command line arguments. This part of the code is tested by
test_regrtest.
This is the first step in refactoring regrtest to use argparse. The
regrtest module's main() function still expects a getopt-style return
value rather than an argparse.Namespace instance.
