bpo-38353: getpath.c: allocates strings on the heap (GH-16585)
* _Py_FindEnvConfigValue() now returns a string allocated
  by PyMem_RawMalloc().
* calculate_init() now decodes VPATH macro.
* Add calculate_open_pyenv() function.
* Add substring() and joinpath2() functions.

* Fix add_exe_suffix()

And a few cleanup changes.

bpo-38353: Add subfunctions to getpath.c (GH-16572)

prevent loops.

Add subfunctions:

* Add resolve_symlinks()
* Add calculate_argv0_path_framework()
* Add calculate_which()
* Add calculate_program_macos()

Fix also _Py_wreadlink(): readlink() result type is Py_ssize_t, not
int.

bpo-38304: Remove PyConfig.struct_size (GH-16500) (GH-16508)
For now, we'll rely on the fact that the config structures aren't covered by the stable ABI.

We may revisit this in the future if we further explore the idea of offering a stable embedding API.

* Make PyWideStringList_INIT macro private: replace "Py" prefix
  with "_Py".
* test_embed: add test_init_warnoptions().

bpo-38304: Add PyConfig.struct_size (GH-16451)
Add a new struct_size field to PyPreConfig and PyConfig structures to
allow to modify these structures in the future without breaking the
backward compatibility.

* Replace private _config_version field with public struct_size field
  in PyPreConfig and PyConfig.
* Public PyPreConfig_InitIsolatedConfig() and
  PyPreConfig_InitPythonConfig()
  return type becomes PyStatus, instead of void.
* Internal _PyConfig_InitCompatConfig(),
  _PyPreConfig_InitCompatConfig(), _PyPreConfig_InitFromConfig(),
  _PyPreConfig_InitFromPreConfig() return type becomes PyStatus,
  instead of void.
* Remove _Py_CONFIG_VERSION
* Update the Initialization Configuration documentation.

bpo-38234: Add test_init_setpath_config() to test_embed (GH-16402)
* Add test_embed.test_init_setpath_config(): test Py_SetPath()
  with PyConfig.
* test_init_setpath() and test_init_setpythonhome() no longer call
  Py_SetProgramName(), but use the default program name.
* _PyPathConfig: isolated, site_import  and base_executable
  fields are now only available on Windows.
* If executable is set explicitly in the configuration, ignore
  calculated base_executable: _PyConfig_InitPathConfig() copies
  executable to base_executable.
* Complete path config documentation.

bpo-38234: Fix _PyConfig_InitPathConfig() (GH-16335)
* _PyConfig_InitPathConfig() now starts by copying the global path
  configuration, and then override values set in PyConfig.
* _PyPathConfig_Calculate() implementations no longer override
  _PyPathConfig fields which are already computed. For example,
  if _PyPathConfig.prefix is not NULL, leave it unchanged.
* If Py_SetPath() has been called, _PyConfig_InitPathConfig() doesn't
  call _PyPathConfig_Calculate() anymore.
* _PyPathConfig_Calculate() no longer uses PyConfig,
  except to initialize PyCalculatePath structure.
* pathconfig_calculate(): remove useless temporary
  "_PyPathConfig new_config" variable.
* calculate_module_search_path(): remove hack to workaround memory
  allocation failure, call Py_FatalError() instead.
* Fix get_program_full_path(): handle memory allocation failure.

bpo-38234: Remove _PyPathConfig.dll_path (GH-16307)
The DLL path is not computed from any user configuration and cannot
be configured by PyConfig. Instead, add a new _Py_dll_path global variable.

Remove _PyConfig_SetPathConfig(): replaced with _PyPathConfig_Init().

Py_Initialize() now longer sets the "global path configuration",
but only initialize _Py_dll_path.

bpo-37206: Unrepresentable default values no longer represented as None. (GH-13933)
In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values
(like in the optional third parameter of getattr). "None" should be used if None is accepted
as argument and passing None has the same effect as not passing the argument at all.

Greg Price 3a4f66707e Cut disused recode_encoding logic in _PyBytes_DecodeEscape. (GH-16013)
All call sites pass NULL for `recode_encoding`, so this path is
completely untested.  That's been true since before Python 3.0.
It adds significant complexity to this logic, so it's best to
take it out.

All call sites now have a literal NULL, and that's been true since
commit 768921cf3 eliminated a conditional (`foo ? bar : NULL`) at
the call site in Python/ast.c where we're parsing a bytes literal.
But even before then, that condition `foo` had been a constant
since unadorned string literals started meaning Unicode, in commit
572dbf8f1 aka v3.0a1~1035 .

The `unicode` parameter is already unused, so mark it as unused too.
The code that acted on it was also taken out before Python 3.0, in
commit 8d30cc014 aka v3.0a1~1031 .

The function (PyBytes_DecodeEscape) is exposed in the API, but it's
never been documented.

Dino Viehland ac46eb4ad6 bpo-38113: Update the Python-ast.c generator to PEP384 (gh-15957)
Summary: This mostly migrates Python-ast.c to PEP384 and removes all statics from the whole file. This modifies the generator itself that generates the Python-ast.c. It leaves in the usage of _PyObject_LookupAttr even though it's not fully PEP384 compatible (this could always be shimmed in by anyone who needs it).
