gh-119960: Add information about regex flags in re module functions (GH-119978)
(cherry picked from commit a86e6255c3)
Co-authored-by: Awbert <119314310+SweetyAngel@users.noreply.github.com>
The `inspect.ismethoddescriptor()` function did not check for the lack of
`__delete__()` and, consequently, erroneously returned True when applied
to *data* descriptors with only `__get__()` and `__delete__()` defined.

This exposes `PyUnstable_Object_ClearWeakRefsNoCallbacks` as an unstable
C-API function to provide a thread-safe mechanism for clearing weakrefs
without executing callbacks.
Some C-API extensions need to clear weakrefs without calling callbacks,
such as after running finalizers like we do in subtype_dealloc.
Previously they could use `_PyWeakref_ClearRef` on each weakref, but
that's not thread-safe in the free-threaded build.

gh-118596: Add thread-safety clarifications to the SSLContext documentation (GH-118597)
Add thread-safety clarifications to the SSLContext documentation. Per the issue:
This issue has also come up [here](https://github.com/psf/requests/pull/6667) where the matter was clarified by @tiran in [this comment](https://github.com/psf/requests/pull/6667):
> `SSLContext` is designed to be shared and used for multiple connections. It is thread safe as long as you don't reconfigure it once it is used by a connection. Adding new certs to the internal trust store is fine, but changing ciphers, verification settings, or mTLS certs can lead to surprising behavior. The problem is unrelated to threads and can even occur in a single-threaded program.

gh-112346: Always set OS byte to 255, simpler gzip.compress function. (GH-120486)
This matches the output behavior in 3.10 and earlier; the optimization in 3.11 allowed the zlib library's "os" value to be filled in instead in the circumstance when mtime was 0. this keeps things consistent.

(cherry picked from commit 81d6336230)
- Explicit list of what it does that is different from
"just return __annotations__"
- Remove reference to PEP 563; adding the future import doesn't
do anything to type aliases, and in general it will never make
get_type_hints() less likely to fail.
- Remove example, as the Annotated docs already have a similar
example, and it's unbalanced to have one example about this
one edge case but not about other behaviors of the function.

PEP 667's description of the planned changes to PyEval_GetLocals
was internally inconsistent when accepted, so the docs added for
gh-74929 didn't match either the current behaviour or the intended
behaviour once gh-118934 is fixed.
This PR updates the documentation and 3.13 What's New to match the
intended behaviour (once gh-118934 is fixed).
It also tidies up lingering references to `f_locals` always being a
dictionary (this hasn't been true since at least when custom
namespace support for class statement execution was added)

* Remove the equivalence with real+imag*1j which can be incorrect in corner
cases (non-finite numbers, the sign of zeroes).
* Separately document the three roles of the constructor: parsing a string,
converting a number, and constructing a complex from components.
* Document positional-only parameters of complex(), float(), int() and bool()
as positional-only.
* Add examples for complex() and int().
* Specify the grammar of the string for complex().
* Improve the grammar of the string for float().
* Describe more explicitly the behavior when real and/or imag arguments are
complex numbers. (This will be deprecated in future.)
