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.
Use the new `PathBase.scandir()` method in `PathBase.glob()`, which greatly
reduces the number of `PathBase.stat()` calls needed when globbing.
There are no user-facing changes, because the pathlib ABCs are still
private and `Path.glob()` doesn't use the implementation in its superclass.
* Remove references to `Modules/_blake2`.
* Remove `Modules/_blake2` entry from CODEOWNERS
The folder does not exist anymore.
* Remove `Modules/_blake2` entry from `Tools/c-analyzer/TODO`
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.
Add `pathlib.Path.scandir()` as a trivial wrapper of `os.scandir()`. This
will be used to implement several `PathBase` methods more efficiently,
including methods that provide `Path.copy()`.
Update time.rst to use `the same clock as` instead of `the same clock than`
The time documentation uses the same clock than time.monotonic instead of the same clock as time.monotonic, which is grammatically false. This PR fixes changes two instances of `the same clock than` to `the same clock as`.
Avoid temporary tuple creation when all arguments either positional-only
or vararg.
Objects/setobject.c and Modules/gcmodule.c adapted. This fixes slight
performance regression for set methods, introduced by gh-115112.
Tarfile in the default write mode spends much of its time resolving UIDs
into usernames and GIDs into group names. By caching these mappings, a
significant speedup can be achieved.
In my simple benchmark[1], this extra caching speeds up tarfile by 8x.
