Fix setup.py on macOS: only add /usr/include/ffi to include
directories of _ctypes, not for all extensions.

* Move fields from _PyMain to _PyCoreConfig:

  * skip_first_line
  * run_command
  * run_module
  * run_filename

* Replace _PyMain.stdin_is_interactive with a new
  stdin_is_interactive(config) function
* Rename _PyMain to _PyArgv. Add "const _PyArgv *args" field
  to _PyCmdline.

Add a new _Py_INIT_EXIT() macro to be able to exit Python with an
exitcode using _PyInitError API. Rewrite function calls by
pymain_main() to use _PyInitError.

Changes:

* Remove _PyMain.err and _PyMain.status field
* Add _Py_INIT_EXIT() macro and _PyInitError.exitcode field.
* Rename _Py_FatalInitError() to _Py_ExitInitError().

Remove colorizer.ColorDelegator.close_when_done and the corresponding argument of .close().  In IDLE, both have always been None or False since 2007.

The whole coreconfig.h header is now excluded from Py_LIMITED_API.
Move functions definitions into a new internal pycore_coreconfig.h
header.

* Move Include/coreconfig.h to Include/cpython/coreconfig.h
* coreconfig.h header is now excluded from Py_LIMITED_API
* Move functions to pycore_coreconfig.h

Use locale.getpreferredencoding() rather than locale.getlocale() to
get the locale encoding. With some locales, locale.getlocale()
returns the wrong encoding.

For example, on Fedora 29, locale.getlocale() returns ISO-8859-1
encoding for the "en_IN" locale, whereas
locale.getpreferredencoding() reports the correct encoding: UTF-8.

* Rename globals to upper case to better distinguish if a variable is
  global or local:

  * Rename cross_compiling to CROSS_COMPILING
  * Rename host_platform to HOST_PLATFORM
  * Rename disabled_module_list to DISABLED_MODULE_LIST

* Add MS_WINDOWS, CYGWIN and MACOS constants.
* Use booleans: replace "return 0" with "return False"
  and replace "return 1" with "return True"

Did you know an API documented as printing the pending traceback would sometimes exit the process?

You do now.

Use longer timeout for accept() in the server and block on accept in the client.
The client now only sets the timeout once the socket is connected.

bpo-35652: shutil.copytree(copy_function=...) erroneously pass DirEntry instead of path str (GH-11997)

a24107b0 introduced a few refleaks.

The standard math library (libm) may follow IEEE-754 recommendation to
include an implementation of sinPi(), i.e. sinPi(x):=sin(pi*x).
And this triggers a name clash, found by FreeBSD developer
Steve Kargl, who worken on putting sinpi into libm used on FreeBSD
(it has to be named "sinpi", not "sinPi", cf. e.g.
https://en.cppreference.com/w/c/experimental/fpext4).

Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

Fixing the test will prevent false positives with pedantic compilers like clang.

Python 3.8.0a2

Deprecate using the __int__() method in implicit conversions of Python
numbers to C integers.

More specifically, the options of --check-hash-based-pycs.

This involves moving the global "pending calls" state to PyInterpreterState.
