subclasses of list or dict and haven't implemented any pickle-related
methods (__reduce__, __reduce_ex__, __getnewargs__, __getnewargs_ex__,
or __getstate__), can no longer be pickled.  Including memoryview.

This patch is manually crafted and contains changes that couldn't be handled
automatically.

The patch is automatically generated, it replaces the code that uses Py_CLEAR.

macro Py_SETREF.

Added tests for dict views.

This allows sys.getsize() to work correctly with their subclasses with
__slots__ defined.

and some tests no longer behaves incorrectly in the presence of the
PYTHONHASHSEED environment variable.

Initialize package before calling get_loader() for __main__, so that we do
not incorrectly handle ImportError from __init__.py. When runpy is used from
the Python CLI, use an internal exception rather than ImportError, to avoid
catching an unexpected ImportError.

Also simplify message formatting: str() is redundant with %s.

Also fix test_dash_m_error_code_is_one() in test_cmd_line_script, which was
failing because the test package was not in the current directlry, rather
the desired ValueError.
