Eric Snow 2ebc5ce42a bpo-30860: Consolidate stateful runtime globals. (#3397)
* group the (stateful) runtime globals into various topical structs
* consolidate the topical structs under a single top-level _PyRuntimeState struct
* add a check-c-globals.py script that helps identify runtime globals

Other globals are excluded (see globals.txt and check-c-globals.py).

Victor Stinner 0f7b0b397e bpo-29735: Optimize partial_call(): avoid tuple (#516)
* Add _PyObject_HasFastCall()

  for positional arguments.
* Fix also a performance regression in partial_call() if the callable
  doesn't support FASTCALL.
