The main change is the introduction of "Python Configuration" and
"Isolated Configuration" default configuration which are well better
defined. Replace all macros with functions.
Changes:
* PyPreConfig: no longer uses dynamically memory allocation,
allocator type becomes an enum, add parse_argv and configure_locale
field.
* PyConfig: Remove program field, rename module_search_path_env to
pythonpath_env
* New functions:
* PyPreConfig_InitIsolatedConfig()
* PyPreConfig_InitPythonConfig()
* PyConfig_InitIsolatedConfig()
* PyConfig_InitPythonConfig()
* parse_argv default becomes 0
* Replace Py_INIT_xxx() macros with functions
* Document default values
* Remove PyConfig.dll_path
* Explain how PyConfig preinitializes Python and the relationship
between command line arguments and the pre-initialization.
* Rename use_module_search_paths to module_search_paths_set
* Rename PyInitError_Err() to PyInitError_Error()
* "Pre-initialization" => "Preinitialization"
* Reject preconfig=NULL and config=NULL
* Replace "wchar_t**" with "wchar_t * const *", same for "char**".
* Thomas Wouters is now the BDFL-delegate
* Elaborate the Rationale
* New "Path configuration" section
* New "Python Issues" section
* Add PyWideStringList_Insert() function
* Add PyConfig.configure_c_stdio option.
* Add PyConfig.parse_argv field
* Rename bytes/wide functions. Add "Bytes" to functions taking char*,
remove "Wide" from functions taking wchar_t*. Rename
PyConfig_DecodeLocale() to PyConfig_SetBytesString().
* PyConfig: Rename '_frozen' to 'pathconfig_warnings'
* Re-introduce PyConfig._init_main
* Complete tables of global configuration variables; annotate
variable values which are negated.
* Add default values of all PyPreConfig and PyConfig fields
* Elaborate the Rationale
* Add a few more issues
* Add PyPreConfig.legacy_windows_fs_encoding rules
* Add "Isolate Python" section
* PyConfig_SetString() and PyConfig_SetBytesString() now requires the
configuration as the first argument.
* Rename Py_UnixMain() to Py_BytesMain()
