Issue #17408: Avoid using an obsolete instance of the copyreg module when the interpreter is shutdown and then started again.

Issue #14928: Fix importlib bootstrap issues by using a custom executable (Modules/_freeze_importlib) to build Python/importlib.h.

importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

  environment variable, to provide an opt-in way to protect against denial of
  service attacks due to hash collisions within the dict and set types.  Patch
  by David Malcolm, based on work by Victor Stinner.

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.

interpreter is shutting down; instead, these threads are now killed when
they try to take the GIL.

limited API.

Add an "optimize" parameter to compile() to control the optimization level, and provide an interface to it in py_compile, compileall and PyZipFile.

Add a Py_SetPath api to override magic path computations when starting up python.

  POSIX systems with a C extension module.  This is required in order for
  the subprocess module to be made thread safe.

  The pure python implementation is retained so that it can continue to be
  used if for some reason the _posixsubprocess extension module is not
  available.

  The unittest executes tests on both code paths to guarantee compatibility.

* Moves PyLong_FromPid and PyLong_AsPid from posixmodule.c into longobject.h.

  and socket.ioctl is enabled only when using a more recent Platform SDK.

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.

renamed Include/bytesobject.h to Include/bytearrayobject.h
renamed Include/stringobject.h to Include/bytesobject.h
added Include/stringobject.h with aliases

Fixes #2128.

The new PyParser_*Ex() functions are based on Neal's suggestion and initial patch. The new __future__ feature makes all '' and r'' unicode strings. b'' and br'' stay (byte) strings.
