bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030)
...
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments. This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

* 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).

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).
