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).

bf623ae884 bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096) 
raised an error.

Replace them with using concrete types API that never fails if appropriate.

5cd87a8d61 Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing. 
Decreased density gives better collision statistics (average of 2.5 probes in a
full table versus 3.0 previously) and fewer occurences of starting a second
possibly overlapping sequence of 10 linear probes.  Makes resizes a little more
frequent but each with less work (fewer insertions and fewer collisions).
