#10166: rewrite self-recursion to iteration in pstats.Stats.add().  Also add a unittest and a stats test file.

Fixes bug #10126 for Python 3.2 by using $RUNSHARED to find the
directory to the shared library.  test_distutils now passes when
Python was built with --enable-shared (Barry didn’t have the error
but I did).

unreadable by all users, e.g., Flash, Silverlight, and Java keys were
causing errors.

We don't currently have a way to grant/deny permissions for a key
via winreg so there are no tests for this.

They can be retrieved through a new attribute `sys._xoptions`.

#9095, #8912, #8999: add support in patchcheck for Mercurial checkouts, C file reindenting, and docs whitespace fixing.

the locale encoding. If the LANG (and LC_ALL and LC_CTYPE) environment variable
is not set, the locale encoding is ISO-8859-1, whereas most programs (including
Python) expect UTF-8. Python already uses UTF-8 for the filesystem encoding and
to encode command line arguments on this OS.

The test failed with python -bb.

Without this patch you'll get link errors in some extensions
(in particular the _curses_panel) one when you try to build
a 3-way universal framework when you previously installed a
2-way universal framework using the python.org installer.

Without this patch the i386/x86_64 installer for OSX 10.6
lies in the ReadMe file and the "Important Information" screen
of the installer (that is, the installer claims it supports
the i386 and ppc architectures insetead of the ones it really
supports)

#10092: Properly reset locale in Locale*Calendar classes.  The context manager was buggy because setlocale() returns the *new* locale, not the old.  Also add a test for this.

Thanks Boštjan Mejak for the patch.

logging: Added _logRecordClass, getLogRecordClass, setLogRecordClass to increase flexibility of LogRecord creation.

Don't fallback to utf-8 anymore to avoid mojibake. I never got any error from
his function.

PyErr_Format() and PyUnicode_FromFormat() are able to allocate the right buffer
size and to catch memory allocation failures.

UTF-8 is just fine for module names.
