Fix the gdb pretty printer in the face of --enable-shared by delaying the attempt to load the _PyInterpreterFrame definition until after .so files are loaded.
- Explicit memory management for `None` objects (since we still try to treat immortal objects as regular objects)
- Respect possible errors of `sys.monitoring.register_callback` call
Replace the os.environ.refresh() method with a new
os.reload_environ() function.

Add missing ``allow_unnamed_section`` parameter to ``ConfigParser`` doc, as well as to it's parent ``RawConfigParser``.
Split too long line on ``ConfigParser`` signature.
Add some sections about when some of ``RawConfigParser`` parameters were added.
The implementation of `Path.glob()` does rather a hacky thing: it calls
`self.with_segments()` to convert the given pattern to a `Path` object, and
then peeks at the private `_raw_path` attribute to see if pathlib removed a
trailing slash from the pattern.
In this patch, we make `glob()` use a new `_parse_pattern()` classmethod
that splits the pattern into parts while preserving information about any
trailing slash. This skips the cost of creating a `Path` object, and avoids
some path anchor normalization, which makes `Path.glob()` slightly faster.
But mostly it's about making the code less naughty.

Each thread specializes a thread-local copy of the bytecode, created on the first RESUME, in free-threaded builds. All copies of the bytecode for a code object are stored in the co_tlbc array on the code object. Threads reserve a globally unique index identifying its copy of the bytecode in all co_tlbc arrays at thread creation and release the index at thread destruction. The first entry in every co_tlbc array always points to the "main" copy of the bytecode that is stored at the end of the code object. This ensures that no bytecode is copied for programs that do not use threads.
Thread-local bytecode can be disabled at runtime by providing either -X tlbc=0 or PYTHON_TLBC=0. Disabling thread-local bytecode also disables specialization.
Concurrent modifications to the bytecode made by the specializing interpreter and instrumentation use atomics, with specialization taking care not to overwrite an instruction that was instrumented concurrently.

GH-113977, GH-120754: Remove unbounded reads from zipfile
Read without a size may read an unbounded amount of data + allocate
unbounded size buffers. Move to capped size reads to prevent potential
issues.

* gh-99880: document rounding mode for new-style formatting
The CPython uses _Py_dg_dtoa(), which does rounding to nearest with half
to even tie-breaking rule.
If that functions is unavailable, PyOS_double_to_string() fallbacks to
system snprintf(). Since CPython 3.12, build requirements include C11
compiler *and* support for IEEE 754 floating point numbers (Annex F).
This means that FE_TONEAREST macro is available and, per default,
printf-like functions should use same rounding mode as _Py_dg_dtoa().

Temporarily ignore warnings about JIT deactivation when perf support is active.
This will be reverted as soon as a way is found to determine at run time whether the interpreter was built with JIT. Currently, this is not possible on Windows.

Performed an audit of `fileio.c` and `_pyio` and made sure anytime the
fd changes the stat result, if set, is also cleared/changed.
There's one case where it's not cleared, if code would clear it in
__init__, keep the memory allocated and just do another fstat with the
existing memory.

* docs: add a more precise example
Previous example used manual integer value assignment in class based declaration but in functional syntax has been used auto value assignment what could be confusing for the new users. Additionally documentation doesn't show how to declare new enum via functional syntax with usage of the manual value assignment.
* docs: remove whitespace characters
* refactor: change example

Use the new `PathBase.scandir()` method in `PathBase.walk()`, which greatly
reduces the number of `PathBase.stat()` calls needed when walking.
There are no user-facing changes, because the pathlib ABCs are still
private and `Path.walk()` doesn't use the implementation in its superclass.

The cases generator inserts code to save and restore the stack pointer around
statements that contain escaping calls. To find the beginning of such statements,
we would walk backwards from the escaping call until we encountered a token that
was treated as a statement terminator. This set of terminators should include
preprocessor directives.
