bpo-46675: Allow object value arrays and split key dictionaries larger than 16 (GH-31191) 2022-02-08 11:50:38 +00:00

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-45340: Don't create object dictionaries unless actually needed (GH-28802)
