gh-117657: Acquire a critical section around `SemLock.__{enter,exit}__` (#118812)
These methods are purely wrappers around `Semlock.{acquire,release}`,
which expect a critical section to be held.

gh-117435: Make `SemLock` thread-safe in free-threaded build (#117436)

gh-107913: Fix possible losses of OSError error codes (GH-107930)
Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be
called immediately after using the C API which sets errno or the Windows
error code.

bpo-15999: Accept arbitrary values for boolean parameters. (#15609)
builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)
Fix invalid function cast warnings with gcc 8

Siddhesh Poyarekar 55edd0c185 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.

* bpo-6532: Make the thread id an unsigned integer.

From C API side the type of results of PyThread_start_new_thread() and
PyThread_get_thread_ident(), the id parameter of
PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState
changed from "long" to "unsigned long".

* Restore a check in thread_get_ident().
