The dataclasses `__init__` function is generated dynamically by a call to `exec()` and so doesn't have deferred reference counting enabled. Enable deferred reference counting on functions when assigned as an attribute to type objects to avoid reference count contention when creating dataclass instances.

gh-141570: can_colorize: Expect fileno() to raise OSError, as documented (GH-141716)
In Fedora, we've been given a slightly incomplete reproducer for a problematic
Python 3.14 color-related change in argparse that leads to an exception when
Python is used from mod_wsgi: https://bugzilla.redhat.com/2414940
mod_wsgi replaces sys.stdout with a custom object that raises OSError on .fileno():
8460dbfcd5/src/server/wsgi_logger.c (L434-L440)
This should be supported, as the documentation of fileno explicitly says:
> An OSError is raised if the IO object does not use a file descriptor.
https://docs.python.org/3.14/library/io.html#io.IOBase.fileno
The previously expected exception inherits from OSError,
so it is still expected.
Fixes https://github.com/python/cpython/issues/141570

gh-136057: Allow step and next to step over for loops (GH-136160)
(cherry picked from commit 8be3b2f479)
Co-authored-by: Tian Gao <gaogaotiantian@hotmail.com>
This splits the OS API specific functionality to get the number of threads out
from the fallback Python method and warning raising code itself. This way the
OS APIs can be queried before we've run
`os.register_at_fork(after_in_parent=...)` registered functions which
themselves may (re)start threads that would otherwise be detected.
This is best effort. If the OS APIs are either unavailable or fail, the
warning generating code still falls back to looking at the Python threading
state after the CPython interpreter world has been restarted and the
after_in_parent calls have been made. The common case for most Linux and macOS
environments should work today.
This also lines up with the existing TODO refactoring, we may choose to expose
this API to get the number of OS threads in the `os` module in the future.
Note: This is a simplified backport that maintains the void return type
for warn_about_fork_with_threads() and keeps PyErr_Clear() in the warning path,
as the error handling changes from fd8f42d3d1 are not needed in 3.14.
