* bpo-9566: Silence warnings from pyatomic.h macros
Apparently MSVC is too stupid to understand that the alternate branch is
not taken and emits a warning for it.
Warnings added in https://github.com/python/cpython/pull/2383
* bpo-9566: A better fix for the pyatomic.h warning
* bpo-9566: Remove a slash

_Py_atomic_* are currently not implemented as atomic operations
when building with MSVC. This patch attempts to implement parts
of the functionality required.

Issue #26161: Use Py_uintptr_t instead of void* for atomic pointers in
pyatomic.h. Use atomic_uintptr_t when <stdatomic.h> is used.
Using void* causes compilation warnings depending on which implementation of
atomic types is used.

Python.h header to fix a compilation error with OpenMP. PyThreadState_GET()
becomes an alias to PyThreadState_Get() to avoid ABI incompatibilies.
It is important that the _PyThreadState_Current variable is always accessed
with the same implementation of pyatomic.h. Use the PyThreadState_Get()
function so extension modules will all reuse the same implementation.

Disable completly pyatomic.h on C++, because <stdatomic.h> is not compatible with C++.
<pyatomic.h> is only needed by the optimized PyThreadState_GET() macro in
pystate.h. Instead, declare PyThreadState_GET() as an alias to
PyThreadState_Get(), as done for limited API.

This allows compiling extension modules with -Wswitch-enum on gcc.

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.
