bpo-30860: Consolidate stateful runtime globals. (#2594)
* 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).

Semaphores are available on Windows XP (2003 server) and later.

We use a Semaphore rather than an auto-reset event, because although

an auto-resent event might appear to solve the lost-wakeup bug (race

condition between releasing the outer lock and waiting) because it
61+
maintains state even though a wait hasn't happened, there is still
62+
a lost wakeup problem if more than one thread are interrupted in the

critical place. A semaphore solves that, because its state is
64+
counted, not Boolean.
65+
Because it is ok to signal a condition variable with no one
66+
waiting, we need to keep track of the number of
67+
waiting threads. Otherwise, the semaphore's state could rise
68+
without bound. This also helps reduce the number of "spurious wakeups"

that would otherwise happen.
