* bpo-41194: Pass module state in Python-ast.c (GH-21284)
Rework asdl_c.py to pass the module state to functions in
Python-ast.c, instead of using astmodulestate_global.
Handle also PyState_AddModule() failure in init_types().
(cherry picked from commit 74419f0c64)
* bpo-41194: The _ast module cannot be loaded more than once (GH-21290)
Fix a crash in the _ast module: it can no longer be loaded more than
once. It now uses a global state rather than a module state.
* Move _ast module state: use a global state instead.
* Set _astmodule.m_size to -1, so the extension cannot be loaded more
than once.

This commit changes the parsing of f-string expressions with the new parser. The parser gets pre-fed with the location of the expression itself (not the f-string, which was what we were doing before). This allows us to completely skip the shifting of the AST nodes after the parsing is completed..

When a file ends with a line that contains a line continuation character
the text of the emitted SyntaxError is empty, contrary to the old
parser, where the error text contained the text of the last line.

On Windows, GH-include "pyerrors.h" no longer defines "snprintf" and
"vsnprintf" macros.
PyOS_snprintf() and PyOS_vsnprintf() should be used to get portable
behavior.
Replace snprintf() calls with PyOS_snprintf() and replace vsnprintf()
calls with PyOS_vsnprintf().

Export explicitly the Py_GetArgcArgv() function to the C API and
document the function. Previously, it was exported implicitly which
no longer works since Python is built with -fvisibility=hidden.
* Add PyConfig._orig_argv member.
* Py_InitializeFromConfig() no longer calls _PyConfig_Write() twice.
* PyConfig_Read() no longer initializes Py_GetArgcArgv(): it is now
_PyConfig_Write() responsibility.
* _PyConfig_Write() result type becomes PyStatus instead of void.
* Write an unit test on Py_GetArgcArgv().
(cherry picked from commit e81f6e687d)
* Provide native .files support on SourceFileLoader.
* Add native importlib.resources.files() support to zipimporter. Remove fallback support.
* make regen-all
* 📜🤖 Added by blurb_it.
* Move 'files' into the ResourceReader so it can carry the relevant module name context.
* Create 'importlib.readers' module and add FileReader to it.
* Add zip reader and rely on it for a TraversableResources object on zipimporter.
* Remove TraversableAdapter, no longer needed.
* Update blurb.
* Replace backslashes with forward slashes.
* Incorporate changes from importlib_metadata 2.0, finalizing the interface for extension via get_resource_reader.
