  Add lib2to3.__main__ for easy testing from the console.

Fix the test for last module changes (r88520).

On Windows, input() strips '\r' (and not only '\n'), and sys.stdin uses
universal newline (replace '\r\n' by '\n').

regression in _FileInFile which is used in file-like objects returned
by TarFile.extractfile(). The inefficient design of the
_FileInFile.read() method causes various dramatic side-effects and
errors:

  - The data segment of a file member is read completely into memory
    every(!) time a small block is accessed. This is not only slow
    but may cause unexpected MemoryErrors with very large files.
  - Reading members from compressed tar archives is even slower
    because of the excessive backwards seeking which is done when the
    same data segment is read over and over again.
  - As a backwards seek on a TarFile opened in stream mode is not
    possible, using extractfile() fails with a StreamError.

repr(module) uses %R to format module name and filenames, instead of '%s' and
'%U', so surrogates from undecodable bytes in a filename (PEP 383) are escaped.

And as a consequence, mark also name argument of
_PyImport_FindExtensionUnicode() constant too. But I plan to change this
argument type to PyObject* later.

The first argument, fqname, was not used.

This function was not declared in Python public API (in any .h file) and not
documented. Mark it as private to prepare a change of its API.

by making methods() into a module attribute as it is statically calculated.

(probably an OS-related issue with mmap)

The module stored away the 'open' object as found in the global namespace
(which fell through to the built-in namespace) since it defined its own 'open'.
Problem is that if you reloaded the module it then grabbed the 'open' defined
in the previous load, leading to code that infinite recursed. Switched to
simply call builtins.open directly.

Thanks to Nadeem Vawda for the find and an initial fix.

Various tests fail when run under coverage. A primary culprit is refcount tests
which fail as the counts are thrown off by the coverage code. A new decorator
-- test.support.refcount_test -- is used to decorate tests which test refcounts
and to skip them when running under coverage. Other tests simply fail because
of changes in the system (e.g., __local__ suddenly appearing).

Thanks to Kristian Vlaardingerbroek for helping to diagnose the test failures.

called collections.abc, following the pattern used by importlib.abc.  For
backwards compatibility, the names continue to also be imported into the
collections module.

4GB, even on 32-bit builds.  Initial patch by Ross Lagerwall, adapted for
32-bit Windows.

to open door files.

Issue #10830: Fix PyUnicode_FromFormatV("%c") for non-BMP characters on
narrow build.

Issue #11168: Remove filename debug variable from PyEval_EvalFrameEx().
It encoded the Unicode filename to UTF-8, but the encoding fails on
undecodable filename (on surrogate characters) which raises an unexpected
UnicodeEncodeError on recursion limit.

Issue #11169: compileall module uses repr() to format filenames and paths to
escape surrogate characters and show spaces.

Issue #11187: Remove bootstrap code (use ASCII) of
PyUnicode_AsEncodedString(), it was replaced by a better fallback (use
the locale encoding) in PyUnicode_EncodeFSDefault().
