Also change BufferedReader.writable() and BufferedWriter.readable() to always
return False.

of iterators of other mutable sequences: it lefts exhausted even if iterated
array is extended.

Affected classes are generic sequence iterators, iterators of str, bytes,
bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
views and os.scandir() iterator.

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.
