In `urllib.request.url2pathname()`, if the authority resolves to the
current host, discard it. If an authority is present but resolves somewhere
else, then on Windows we return a UNC path (as before), and on other
platforms we raise `URLError`.
Affects `pathlib.Path.from_uri()` in the same way.

Make `warnings.catch_warnings()` use a context variable for holding
the warning filtering state if the `sys.flags.context_aware_warnings`
flag is set to true. This makes using the context manager thread-safe in
multi-threaded programs.
Add the `sys.flags.thread_inherit_context` flag. If true, starting a new
thread with `threading.Thread` will use a copy of the context
from the caller of `Thread.start()`.
Both these flags are set to true by default for the free-threaded build
and false for the default build.
Move the Python implementation of warnings.py into _py_warnings.py.
Make _contextvars a builtin module.

* Add ZipFile.data_offset attribute
This attribute provides the offset to zip data from the start of the file, when available.
* Add blurb-it
* Try fixing class ref in NEWS
The `http.server` module now supports serving over HTTPS using the `http.server.HTTPSServer` class.
This functionality is also exposed by the command-line interface (`python -m http.server`) through the
`--tls-cert`, `--tls-key` and `--tls-password-file` options.
It doesn't make sense to use a deprecation for evaluate_forward_ref,
as it is a new function in Python 3.14 and doesn't have compatibility
guarantees.
I considered making it throw an error if type_params it not passed and
there is no owner. However, I think this is too unfriendly for users. The
case where this param is really needed is fairly esoteric and I don't think
this case is worth the pain of forcing users to write "type_params=()".
Optimize `LOAD_FAST` opcodes into faster versions that load borrowed references onto the operand stack when we can prove that the lifetime of the local outlives the lifetime of the temporary that is loaded onto the stack.
Update os.walk example to be more modern, skip `__pycache__` dirs rather than `CVS` dirs.

* Clarify datetime `replace` documentation
In #115684, HopedForLuck noted that `datetime.date.replace()`
documentation was confusing because it looked like it would be changing
immutable objects.
This documentation change specifies that the `replace()` methods in
`datetime` return new objects. This uses similar wording to the
documentation for `datetime.combine()`, which specifies that a new
datetime is returned. This is also similar to wording for
`string.replace()`, except `string.replace()` emphasizes that a "copy"
is returned.
Resolves#115684.
* Include reviewer comments
Thanks Privat33r-dev for the comments!

- Restore max field size to sys.maxsize, as in Python 3.13 & below
- PyCField: Split out bit/byte sizes/offsets.
- Expose CField's size/offset data to Python code
- Add generic checks for all the test structs/unions, using the newly exposed attrs
Call `urllib.request.pathname2url()` from `pathlib.Path.as_uri()`, and
deprecate the duplicate implementation in `PurePath`.
