gh-128863: Deprecate the private _PyUnicodeWriter API (#129245) 
Deprecate private C API functions:

* _PyUnicodeWriter_Init()
* _PyUnicodeWriter_Finish()

These functions are not deprecated in the internal C API (if the
Py_BUILD_CORE macro is defined).

gh-128844: Make _Py_TryIncref public as an unstable API. (#128926) 
This exposes `_Py_TryIncref` as `PyUnstable_TryIncref()` and the helper
function `_PyObject_SetMaybeWeakref` as `PyUnstable_EnableTryIncRef`.

These are helpers for dealing with unowned references in a safe way,
particularly in the free threading build.

gh-128008: Add PyWeakref_IsDead() (GH-128009) 
The `PyWeakref_IsDead()` function tests if a weak reference is dead
without any side effects. Although you can also detect if a weak
reference is dead using `PyWeakref_GetRef()`, that function returns a
strong reference that must be `Py_DECREF()`'d, which can introduce side
effects if the last reference is concurrently dropped (at least in the
free threading build).

gh-126554: ctypes: Correctly handle NULL dlsym values (GH-126555) 
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.
