bpo-32096, bpo-30860: Partially revert the commit
2ebc5ce42a8a9e047e790aefbf9a94811569b2b6:
* Move structures back from Include/internal/mem.h to
Objects/obmalloc.c
* Remove _PyObject_Initialize() and _PyMem_Initialize()
* Remove Include/internal/pymalloc.h
* Add test_capi.test_pre_initialization_api():
Make sure that it's possible to call Py_DecodeLocale(), and then call
Py_SetProgramName() with the decoded string, before Py_Initialize().
PyMem_RawMalloc() and Py_DecodeLocale() can be called again before
_PyRuntimeState_Init().

Previously, 'msilib.OpenDatabase()' function raised a
cryptical exception message when it couldn't open or
create an MSI file. For example:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
_msi.MSIError: unknown error 6e
create_filter() now expects the action as a _Py_Identifier which
avoids string comparison, and more important, to avoid handling the
"unknown action" annoying case.
* calculate_path() rewritten in Modules/getpath.c and PC/getpathp.c
* Move global variables into a new PyPathConfig structure.
* calculate_path():
* Split the huge calculate_path() function into subfunctions.
* Add PyCalculatePath structure to pass data between subfunctions.
* Document PyCalculatePath fields.
* Move cleanup code into a new calculate_free() subfunction
* calculate_init() now handles Py_DecodeLocale() failures properly
* calculate_path() is now atomic: only replace PyPathConfig
(path_config) at once on success.
* _Py_GetPythonHomeWithConfig() now returns an error on failure
* Add _Py_INIT_NO_MEMORY() helper: report a memory allocation failure
* Coding style fixes (PEP 7)
* Py_Main() now reads the PYTHONHOME environment variable
* Add _Py_GetPythonHomeWithConfig() private function
* Add _PyWarnings_InitWithConfig()
* init_filters() doesn't get the current core configuration from the
current interpreter or Python thread anymore. Pass explicitly the
configuration to _PyWarnings_InitWithConfig().
* _Py_InitializeCore() now fails on _PyWarnings_InitWithConfig()
failure.
* Pass configuration as constant
Adds a simpler and faster alternative to ExitStack for handling
single optional context managers without having to change the
lexical structure of your code.
Changes:
* Py_Main() initializes _PyCoreConfig.module_search_path_env from
the PYTHONPATH environment variable.
* PyInterpreterState_New() now initializes core_config and config
fields
* Compute sys.path a little bit ealier in
_Py_InitializeMainInterpreter() and new_interpreter()
* Add _Py_GetPathWithConfig() private function.
* Optimize warnings.filterwarnings(). Replace re.compile('') with
None to avoid the cost of calling a regex.match() method, whereas
it always matchs.
* Optimize get_warnings_attr(): replace PyObject_GetAttrString() with
_PyObject_GetAttrId().
Cleanup also create_filter():
* Use _Py_IDENTIFIER() to allow to cleanup strings at Python
finalization
* Replace Py_FatalError() with a regular exceptions
* Rename support._match_test() to support.match_test(): make it
public
* Remove support.match_tests global variable. It is replaced with a
new support.set_match_tests() function, so match_test() doesn't
have to check each time if patterns were modified.
* Rewrite match_test(): use different code paths depending on the
kind of patterns for best performances.

Py_Main() now handles two more -X options:
* -X showrefcount: new _PyCoreConfig.show_ref_count field
* -X showalloccount: new _PyCoreConfig.show_alloc_count field
The developer mode (-X dev) now creates all default warnings filters
to order filters in the correct order to always show ResourceWarning
and make BytesWarning depend on the -b option.
Write a functional test to make sure that ResourceWarning is logged
twice at the same location in the developer mode.
Add a new 'dev_mode' field to _PyCoreConfig.
Modify subprocess._args_from_interpreter_flags() to handle -X dev
option.
Add also unit tests for test.support.args_from_interpreter_flags()
and test.support.optim_args_from_interpreter_flags().
When Python is build is debug mode (Py_DEBUG), DeprecationWarning,
PendingDeprecationWarning and ImportWarning warnings are now
displayed by default.
test_venv: run "-m pip" and "-m ensurepip._uninstall" with -W
ignore::DeprecationWarning since pip code is not part of Python.
`BUILD_MAP_UNPACK_WITH_CALL` was duplicated as the opcode for both var-positional and var-keyword arguments. The opcode for the former was updated as `BUILD_TUPLE_UNPACK_WITH_CALL`.
* Run gzip with separate command line options (Android understands '-f9' as the name of a file).
* Creation of a hard link is controled by SELinux on Android.
Remove the following fields from tok_state structure which are now
used unused:
* altwarning: "Issue warning if alternate tabs don't match"
* alterror: "Issue error if alternate tabs don't match"
* alttabsize: "Alternate tab spacing"
Replace alttabsize variable with ALTTABSIZE define.
Add a new "developer mode": new "-X dev" command line option to
enable debug checks at runtime.
Changes:
* Add unit tests for -X dev
* test_cmd_line: replace test.support with support.
* Fix _PyRuntimeState_Fini(): Use the same memory allocator
than _PyRuntimeState_Init().
* Fix _PyMem_GetDefaultRawAllocator()
