gh-127586: multiprocessing.Pool does not properly restore blocked signals (try 2) (GH-128011)
Correct pthread_sigmask in resource_tracker to restore old signals
Using SIG_UNBLOCK to remove blocked "ignored signals" may accidentally
cause side effects if the calling parent already had said signals
blocked to begin with and did not intend to unblock them when
creating a pool. Use SIG_SETMASK instead with the previous mask of
blocked signals to restore the original blocked set.

For dlsym(), a return value of NULL does not necessarily indicate
an error [1].
Therefore, to avoid using stale (or NULL) dlerror() values, we must:
1. clear the previous error state by calling dlerror()
2. call dlsym()
3. call dlerror()
If the return value of dlerror() is not NULL, an error occured.
In ctypes we choose to treat a NULL return value from dlsym()
as a "not found" error. This is the same as the fallback
message we use on Windows, Cygwin or when getting/formatting
the error reason fails.

gh-127906: Skip limited C API test_cext tests if Py_TRACE_REFS

gh-127257: ssl: Raise OSError for ERR_LIB_SYS (GH-127361)
From the ERR_raise manpage:
ERR_LIB_SYS
This "library code" indicates that a system error is
being reported. In this case, the reason code given
to `ERR_raise()` and `ERR_raise_data()` *must* be
`errno(3)`.
This PR only handles ERR_LIB_SYS for the high-lever error types
SSL_ERROR_SYSCALL and SSL_ERROR_SSL, i.e., not the ones where
OpenSSL indicates it has some more information about the issue.

gh-127906: Declare timeval struct in pytime.h on Windows
Fix the following MSVC compiler warning:
include\cpython\pytime.h(192): warning C4115: 'timeval':
named type definition in parentheses
gh-107249: Implement Py_UNUSED() for MSVC (GH-107250)
Fix warnings C4100 in Py_UNUSED() when Python is built with "cl /W4".
Example with this function included by Python.h:
static inline unsigned int
PyUnicode_IS_READY(PyObject* Py_UNUSED(op))
{ return 1; }
Without this change, building a C program with "cl /W4" which just
includes Python.h emits the warning:
Include\cpython/unicodeobject.h(199):
warning C4100: '_unused_op': unreferenced formal parameter
This change fix this warning.
