## Encode header parts that contain newlines
Per RFC 2047:
> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects
It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.
## Verify that email headers are well-formed
This should fail for custom fold() implementations that aren't careful
about newlines.

The adaptive counter doesn't do anything currently in the free-threaded
build and TSan reports a data race due to concurrent modifications to
the counter.
* Authenticate socket connection for `socket.socketpair()` fallback when the platform does not have a native `socketpair` C API. We authenticate in-process using `getsocketname` and `getpeername` (thanks to Nathaniel J Smith for that suggestion).

The tests were only checking cases where the slot wrapper was present in the initial case. They were missing when the slot wrapper was added in the additional initializations. This fixes that.
* Use compensated summation for complex sums with floating-point items.
This amends #121176.
* sum() specializations for floats and complexes now use
PyLong_AsDouble() instead of PyLong_AsLongAndOverflow() and
compensated summation as well.
Change _PyLong_IsCompact() and _PyLong_CompactValue() parameter type
from 'PyObject*' to 'const PyObject*'. Avoid the Py_TYPE() macro
which does not support const parameter.
Re-order table of corresponding functions with the following priorities:
1. Pure functionality is at the top
2. `os.path` functions are shown before `os` functions
3. Similar functionality is kept together
4. Functionality follows docs order where possible
Add a few missed correspondences:
- `os.path.isjunction` and `Path.is_junction`
- `os.path.ismount` and `Path.is_mount`
- `os.lstat()` and `Path.lstat()`
- `os.lchmod()` and `Path.lchmod()`
Also add footnotes describing a few differences.

In the free-threaded build, we need to lock pending->mutex when clearing
the handling_thread in order not to race with a concurrent
make_pending_calls in the same interpreter.
