Pass all regrtest options, not only --testdir.

Pass also --testdir option.

test_forever() stores its state into the builtins module since the test module
is reloaded at each run.

Remove also warning to detect leaked tests of a previous run.

add "test." prefix to test module names.

regrtest also prepends testdir to sys.path.

Use the default timeout of 30 seconds to avoid blocking forever.

Issue #26641: doctest.DocFileTest and doctest.testfile() now support packages
(module splitted into multiple directories) for the package parameter.

* Fix test_os.BytesWalkTests on Windows
* Mimick better the reference os.DirEntry on Windows
* _DummyDirEntry now caches os.stat() result
* _DummyDirEntry constructor now tries to get os.stat()
* Fix os._DummyDirEntry.is_symlink(), don't follow symbolic links:
  use os.stat(path, follow_symlinks=False).

Issue #25911: Fix os._DummyDirEntry.is_symlink(), don't follow symbolic links:
use os.stat(path, follow_symlinks=False).

Thanks Arfrever for the report :)

_Call is a subclass of tuple (changeset 3603bae63c13 only works
for classes) so we need to implement __ne__ ourselves.

If you pass -1, the callable can take any number of arguments.

Added tests to verify the behavior.

The behaviour of the close method is tested by ClosedCurTests
in Lib/sqlite3/test/dbapi.py.

This is basically a backport of https://github.com/ghaering/pysqlite/issues/73.

Move many tests from NetworkedTests and NetworkedBIOTests to a new Simple-
BackgroundTests class, using the existing ThreadedEchoServer and SIGNED_
CERTFILE infrastructure.

For tests that cause the server to crash by rejecting its certificate,
separate them into independent test methods.

Added custom root certificate to capath with the following commands:

cp Lib/test/{pycacert.pem,capath/}
# Edit copy to remove part before certificate
c_rehash -v Lib/test/capath/
c_rehash -v -old Lib/test/capath/
# Note the generated file names
cp Lib/test/capath/{pycacert.pem,b1930218.0}
mv Lib/test/capath/{pycacert.pem,ceff1710.0}

Change to pure PEM version of SIGNING_CA because PEM_cert_to_DER_cert() does
not like the extra text at the start.

Moved test_connect_ex_error() into BasicSocketTests and rewrote it to connect
to a reserved localhost port.

NetworkedTests.test_get_server_certificate_ipv6() split out because it needs
to connect to an IPv6 DNS address.

The only reference left to self-signed.pythontest.net is test_timeout_
connect_ex(), which needs a remote server to reliably time out the
connection, but does not rely on the server running SSL.

Made ThreadedEchoServer call unwrap() by default when it sees the client has
shut the connection down, so that the client can cleanly call unwrap().

See dict.__new__() and list.__new__() for comparison.  Neither of those examine or touch
args or kwds.  That work is done in the __init__() methods.

Issue #20021: use importlib.machinery to import Lib/opcode.py and not an opcode
module coming from somewhere else. makeopcodetargets.py is part of the Python
build process and it is run by an external Python program, not the built Python
program.
