Previously, basic initialization of PyInterprterState happened in PyInterpreterState_New() (along with allocation and adding the new interpreter to the runtime state). This prevented us from initializing interpreter states that were allocated separately (e.g. statically or in a free list). We've addressed that here by factoring out a separate function just for initialization. We've done the same for PyThreadState. _PyRuntimeState was sorted out when we added it since _PyRuntime is statically allocated. However, here we update the existing init code to line up with the functions for PyInterpreterState and PyThreadState.

PyInterpreterState_Main() is a plain function exposed in the public C-API. For internal usage we can take the more efficient approach in this PR.

This simplifies new_threadstate(). We also rename _PyThreadState_Init() to _PyThreadState_SetCurrent() to reflect what it actually does.

Doing so allows us to stop assigning various fields to `NULL` and 0. It also more closely matches the behavior of a static initializer.

This parallels _PyRuntimeState.interpreters. Doing this helps make it more clear what part of PyInterpreterState relates to its threads.

This falls into the category of keep-allocation-and-initialization separate. It also allows us to use _PyEval_InitState() safely in functions that return void.

* Check NS API return values for NULL to prevent segfault in
``_bootstrap_python``.
* Set modPathInitialized to 1 so the ``decode_to_dict`` path is used.

Check that users don't push changes with outdated or patched autoconf.
The presence of runstatedir option and aclocal 1.16.3 are good markers.
Use my container image to regenerate autoconf files. "Check for changes"
will fail later when any file is regenerated.
Use ccache in check_generated_files to speed up testing.
* Make generator, coroutine and async gen structs all the same size.
* Store interpreter frame in generator (and coroutine). Reduces the number of allocations neeeded for a generator from two to one.
For very large numbers use divide-and-conquer algorithm for getting
benefit of Karatsuba multiplication of large numbers.
Do calculations completely in C unsigned long long instead of Python
integers if possible.
