gh-112075: Remove critical section in dict.get (gh-129336) 
The `dict.get` implementation uses `_Py_dict_lookup_threadsafe`, which is
thread-safe, so we remove the critical section from the argument clinic.

Add a test for concurrent dict get and set operations.

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-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.

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}`

gh-128212: Fix race in _PyUnicode_CheckConsistency (GH-128367) 
There was a data race on the utf8 field between `PyUnicode_SET_UTF8` and
`_PyUnicode_CheckConsistency`. Use the `_PyUnicode_UTF8()` accessor,
which uses an atomic load internally, to avoid the data race.
