14514d9084 bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375) 
The final addition (cur += step) may overflow, so use size_t for "cur".
"cur" is always positive (even for negative steps), so it is safe to use
size_t here.

bb86bf4c4e bpo-35444: Unify and optimize the helper for getting a builtin object. (GH-11047) 
This speeds up pickling of some iterators.

This fixes also error handling in pickling methods when fail to
look up builtin "getattr".

27e2d1f219 bpo-35081: Add pycore_ prefix to internal header files (GH-10263) 
* Rename Include/internal/ header files:

  * pyatomic.h -> pycore_atomic.h
  * ceval.h -> pycore_ceval.h
  * condvar.h -> pycore_condvar.h
  * context.h -> pycore_context.h

* Update includes. For example, replace #include "internal/mem.h"
  with #include "pycore_mem.h".

49c75a8086 bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ (GH-10152) 
Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0"
makes "make smelly" fail as some symbols were being exported without the "Py_" or
"_Py" prefixes.

53b7d4e402 bpo-34170: Add _PyCoreConfig.bytes_warning (GH-8447) 
Add more fields to _PyCoreConfig:

* _check_hash_pycs_mode
* bytes_warning
* debug
* inspect
* interactive
* legacy_windows_fs_encoding
* legacy_windows_stdio
* optimization_level
* quiet
* unbuffered_stdio
* user_site_directory
* verbose
* write_bytecode

Changes:

* Remove pymain_get_global_config() and pymain_set_global_config()
  which became useless. These functions have been replaced by
  _PyCoreConfig_GetGlobalConfig() and
  _PyCoreConfig_SetGlobalConfig().
* sys.flags.dont_write_bytecode value is now restricted to 1 even if
  -B option is specified multiple times on the command line.
* PyThreadState_Clear() now uses the config from the current
  interpreter rather than using global Py_VerboseFlag

55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030) 
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.
