Interpreter.call() should be able to support arbitrary callables, full args, and return values.

…eUTF8() (gh-132979) They are derived from the existing `PyModule_GetFilenameObject(). They are used by a later change related to pickle and handling __main__.

We replace it with _Py_GetMainModule(), and add _Py_CheckMainModule(), but both in the internal-only C-API. We also add _PyImport_GetModulesRef(), which is the equivalent of _PyImport_GetModules(), but which increfs before the lock is released. This is used by a later change related to pickle and handling __main__.

This is the base for several other XIData wrappers, like pickle and marshal. It is essentially a refactor of the existing bytes XIData code.

Note that the bulk of this change is tests.

The function indicates whether or not the function has a return statement. This is used by a later change related treating some functions like scripts.

Could you elaborate what the "minor issues" are?
Either as a task list or sub issues?

It isn't clear to me why, for example, #132981 is needed, or if it is the right solution to whatever the problem is.

This helper is useful in a variety of ways, including in demonstrating how the different counts relate to one another. It will be used in a later change to help identify if a function is "stateless", meaning it doesn't have any free vars or globals. Note that a majority of this change is tests.

There's some extra complexity due to making sure we we get things right when handling functions and classes defined in the __main__ module. This is also reflected in the tests, including the addition of extra functions in test.support.import_helper.

This reverts commit 94b4fcd.

The change broke the s390 builds, so I'm reverting it while I investigate. This reverts commit 94b4fcd.

This reverts commit 811edcf (pythongh-133128).

This is mostly a refactor to clean things up a bit, most notably the "XI namespace" code. Making the session opaque requires adding the following internal-only functions: * _PyXI_NewSession() * _PyXI_FreeSession() * _PyXI_GetMainNamespace()
