gh-110850: Rename internal PyTime C API functions (#115734)
Rename functions:

* _PyTime_GetSystemClock() => _PyTime_TimeUnchecked()
* _PyTime_GetPerfCounter() => _PyTime_PerfCounterUnchecked()
* _PyTime_GetMonotonicClock() => _PyTime_MonotonicUnchecked()
* _PyTime_GetSystemClockWithInfo() => _PyTime_TimeWithInfo()
* _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo()
* _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo()

Changes:

* Remove "typedef PyTime_t PyTime_t;" which was
  "typedef PyTime_t _PyTime_t;" before a previous rename.
* Update comments of "Unchecked" functions.
* Remove invalid PyTime_Time() comment.

gh-104061: Add socket.SO_BINDTOIFINDEX constant (GH-104062)
Add socket.SO_BINDTOIFINDEX constant

This socket option avoids a race condition between SO_BINDTODEVICE and network interface renaming.

Tier 2 cleanups and tweaks (#115534)
* Rename `_testinternalcapi.get_{uop,counter}_optimizer` to `new_*_optimizer`
* Use `_PyUOpName()` instead of` _PyOpcode_uop_name[]`
* Add `target` to executor iterator items -- `list(ex)` now returns `(opcode, oparg, target, operand)` quadruples
* Add executor methods `get_opcode()` and `get_oparg()` to get `vmdata.opcode`, `vmdata.oparg`
* Define a helper for printing uops, and unify various places where they are printed
* Add a hack to summarize_stats.py to fix legacy uop names (e.g. `POP_TOP` -> `_POP_TOP`)
* Define helpers in `test_opt.py` for accessing the set or list of opnames of an executor

gh-115103: Implement delayed free mechanism for free-threaded builds (#115367)
This adds `_PyMem_FreeDelayed()` and supporting functions. The
`_PyMem_FreeDelayed()` function frees memory with the same allocator as
`PyMem_Free()`, but after some delay to ensure that concurrent lock-free
readers have finished.

in internal header files. This type is now provided by <Python.h>
include. Add <pycore_time.h> includes to C files instead.

Restore support of such combination, disabled in gh-113796.

csv.writer() now quotes empty fields if delimiter is a space and
skipinitialspace is true and raises exception if quoting is not possible.

ob_ref_shared with debug bytes (e.g., 0xDD) in mimalloc in the
free-threaded build.

gh-112175: Add `eval_breaker` to `PyThreadState` (#115194)
This change adds an `eval_breaker` field to `PyThreadState`. The primary
motivation is for performance in free-threaded builds: with thread-local eval
breakers, we can stop a specific thread (e.g., for an async exception) without
interrupting other threads.

The source of truth for the global instrumentation version is stored in the
`instrumentation_version` field in PyInterpreterState. Threads usually read the
version from their local `eval_breaker`, where it continues to be colocated
with the eval breaker bits.
