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.

Python-ast.c, instead of using astmodulestate_global.
Handle also PyState_AddModule() failure in init_types().

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).
