summary: Changes to allow Profile Guided Optimization builds to succeed on VS2010
and lifetime issues of dynamically allocated Py_buffer members (#9990)
as well as crashes (#8305, #7433). Many new features have been added
(See whatsnew/3.3), and the documentation has been updated extensively.
The ndarray test object from _testbuffer.c implements all aspects of
PEP-3118, so further development towards the complete implementation
of the PEP can proceed in a test-driven manner.
Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
and many ideas.
- Issue #12834: Fix incorrect results of memoryview.tobytes() for
non-contiguous arrays.
- Issue #5231: Introduce memoryview.cast() method that allows changing
format and shape without making a copy of the underlying memory.
in order to make algorithmic complexity attacks on (e.g.) web apps much more complicated.
The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

When the solution is converted to Visual Studio 2010, the command line to invoke make_buildinfo changes from:
$(SolutionDir)make_buildinfo.exe" Debug "$(IntDir)\"
to
$(SolutionDir)make_buildinfo.exe" Debug "$(IntDir)"
If the final backslash is omitted, the backslash in IntDir will escape the quote, thus passing the quote in as part of the path name.
This solution is a hack-fix to that problem by skipping any trailing quote from the path name. It works as long as we don't need any additional arguments to make_buildinfo.exe. This will help all those sould that are going to run this project through the visual studio autoconverter and get the same error.
make_buildinfo regression with unquoted path
Make_buildinfo.exe should be called with a quoted path, and should quote the full paths to its temp files, to support spaces in filenames.
* _Py_fopen() and _Py_stat() come from Python/import.c
* (_Py)_wrealpath() comes from Python/sysmodule.c
* _Py_char2wchar(), _Py_wchar2char() and _Py_wfopen() come from Modules/main.c
* (_Py)_wstat(), (_Py)_wgetcwd(), _Py_wreadlink() come from Modules/getpath.c

Issue #9810: Compile bzip2 source files in python's project file
directly. It used to be built with bzip2's makefile.
........
* pythoncore.vcproj: Fixed indentation
* _multiprocessing.vcproj: Converted ProjectGUID to uppercase. Otherwise,
VS8 _multiprocessing.vcproj created by vs9to8.py was modified every time
loads it in VS8 IDE.

On Windows, ctypes does no longer check the stack before and after
calling a foreign function. This allows to use the unmodified libffi
library.
Remove most files from _ctypes/libffi_msvc, only two include files
stay (updated from _ctypes/libffi/...). Other files are used in the
cross-platform _ctypes/libffi directory.

http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data
race detector that runs on top of valgrind. With this patch, the binaries at
http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many
but not all of the Python tests. All of regrtest still passes outside of tsan.
I've implemented part of the C1x atomic types so that we can explicitly mark
variables that are used across threads, and get defined behavior as compilers
advance.
I've added tsan's client header and implementation to the codebase in
dynamic_annotations.{h,c} (docs at
http://code.google.com/p/data-race-test/wiki/DynamicAnnotations).
Unfortunately, I haven't been able to get helgrind and drd to give sensible
error messages, even when I use their client annotations, so I'm not supporting
them.

Add -Wd to the flags used to run the tests (-3 is not necessary here).

Set svn:eol-style=CRLF on all Visual Studio solution files.
This should allow direct compilation from a downloaded source tar ball.

- incorporate and adapt David Gay's dtoa and strtod
into the Python core
- on platforms where we can use Gay's code (almost
all!), repr(float) is based on the shortest
sequence of decimal digits that rounds correctly.
- add sys.float_repr_style attribute to indicate
whether we're using Gay's code or not
- add autoconf magic to detect and enable SSE2
instructions on x86/gcc
- slight change to repr and str: repr switches
to exponential notation at 1e16 instead of
1e17, str switches at 1e11 instead of 1e12
