bpo-46417: Clear more static types (GH-30796) 
* Move PyContext static types into object.c static_types list.
* Rename PyContextTokenMissing_Type to _PyContextTokenMissing_Type
  and declare it in pycore_context.h.
* _PyHamtItems types are no long exported: replace PyAPI_DATA() with
  extern.

bpo-46008: Make runtime-global object/type lifecycle functions and state consistent. (gh-29998) 
This change is strictly renames and moving code around.  It helps in the following ways:

* ensures type-related init functions focus strictly on one of the three aspects (state, objects, types)
* passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter
* consistent naming conventions help make what's going on more clear
* keeping API related to a type in the corresponding header file makes it more obvious where to look for it

bpo-29882: Add _Py_popcount32() function (GH-20518) 
* Rename pycore_byteswap.h to pycore_bitutils.h.
* Move popcount_digit() to pycore_bitutils.h as _Py_popcount32().
* _Py_popcount32() uses GCC and clang builtin function if available.
* Add unit tests to _Py_popcount32().

PyMemberDef is used.

Jeroen Demeyer 351c67416b bpo-35983: skip trashcan for subclasses (GH-11841) 
Add new trashcan macros to deal with a double deallocation that could occur when the `tp_dealloc` of a subclass calls the `tp_dealloc` of a base class and that base class uses the trashcan mechanism.

Patch by Jeroen Demeyer.

bpo-32436: Fix a refleak; var GC tracking; a GCC warning (#5326) 
The refleak in question wasn't really important, as context vars
are usually created at the toplevel and live as long as the interpreter
lives, so the context var name isn't ever GCed anyways.
