gh-128030: Avoid error from PyModule_GetFilenameObject for non-module (GH-128047)
I missed the extra `PyModule_Check` in GH-127660 because I was looking at
3.12 as the base implementation for import from. This meant that I
missed the `PyModuleCheck` introduced in GH-112661.

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.

Adds a `use_system_log` config item to enable stdout/stderr redirection for
Apple platforms. This log streaming is then used by a new iOS test runner
script, allowing the display of test suite output at runtime. The iOS test
runner script can be used by any Python project, not just the CPython test
suite.

Objects may be temporarily "resurrected" in destructors when calling
finalizers or watcher callbacks. We previously undid the resurrection
by decrementing the reference count using `Py_SET_REFCNT`. This was not
thread-safe because other threads might be accessing the object
(modifying its reference count) if it was exposed by the finalizer,
watcher callback, or temporarily accessed by a racy dictionary or list
access.
This adds internal-only thread-safe functions for temporary object
resurrection during destructors.

gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952)
As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working. This is a minimal fix just to get builds working again. There are actually a number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need to be resolved separately.

Note, that transformed expression is not an equivalent for original one (1/exp(-x) != exp(x) in general for floating-point numbers). Though, the difference seems to be ~1ULP for good libm implementations.
It's more interesting why division was used from beginning. Closest algorithm I've found (no error checks, of course;)) - it's Algorithm 190 from ACM: https://dl.acm.org/doi/10.1145/366663.366679. It uses subtraction in the exponent.

Since MultiByteToWideChar()/WideCharToMultiByte() is not reversible if
the data contains invalid UTF-8 sequences, use binary search to
calculate the number of written bytes from the number of written
characters.
Also fix writing incomplete UTF-8 sequences.
Also fix handling of memory allocation failures.
