* _PyDict_GetItemStringWithError()
* _PyDict_Pop()
* _PyThreadState_UncheckedGet()
* _PyUnicode_AsString()

gh-128902: Fix check for fallthrough attribute support (#128903) 
Clang versions prior to 10 (which corresponds to Apple Clang 12) do not
support the GCC extension syntax __attribute__((fallthrough)), but do
evaluate __has_attribute(fallthrough) to 1 because they support the
C++11 style syntax [[fallthrough]]. The only way to tell if the GCC
style syntax is supported is thus to check the clang version.

gh-128923: Use zero to indicate unassigned unique id (#128925) 
In the free threading build, the per thread reference counting uses a
unique id for some objects to index into the local reference count
table. Use 0 instead of -1 to indicate that the id is not assigned. This
avoids bugs where zero-initialized heap type objects look like they have
a unique id assigned.

* Use TABLES_LOCK() to protect 'tracemalloc_config.tracing'.
* Hold TABLES_LOCK() longer while accessing tables.
* tracemalloc_realloc() and tracemalloc_free() no longer
  remove the trace on reentrant call.
* _PyTraceMalloc_Stop() unregisters _PyTraceMalloc_TraceRef().
* _PyTraceMalloc_GetTraces() sets the reentrant flag.
* tracemalloc_clear_traces_unlocked() sets the reentrant flag.

gh-127787: refactor helpers for PyUnicodeErrorObject internal interface (GH-127789) 
- Unify `get_unicode` and `get_string` in a single function.

- Allow to retrieve the underlying `object` attribute, its
  size, and the adjusted 'start' and 'end', all at once.
  Add a new `_PyUnicodeError_GetParams` internal function for this.
  (In `exceptions.c`, it's somewhat common to not need all the attributes,
  but the compiler has opportunity to inline the function and optimize
  unneeded work away. Outside that file, we'll usually need all or
  most of them at once.)

- Use a common implementation for the following functions:

  - `PyUnicode{Decode,Encode}Error_GetEncoding`
  - `PyUnicode{Decode,Encode,Translate}Error_GetObject`
  - `PyUnicode{Decode,Encode,Translate}Error_{Get,Set}Reason`
  - `PyUnicode{Decode,Encode,Translate}Error_{Get,Set}{Start,End}`
