* Restore the slash-prefixed paths in the malformed_paths test.
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.

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).

Remove extra self DECREF on ssl "no ciphers" error path.
This doesn't come up in practice because nobody links against a broken
OpenSSL library that provides nothing.

[3.12] gh-83434: Sync libregrtest and test_regrtest with the main branch (GH-117250)
* gh-115122: Add --bisect option to regrtest (GH-115123)
* test.bisect_cmd now exit with code 0 on success, and code 1 on
failure. Before, it was the opposite.
* test.bisect_cmd now runs the test worker process with
-X faulthandler.
* regrtest RunTests: Add create_python_cmd() and bisect_cmd()
methods.

* gh-115720: Show number of leaks in huntrleaks progress reports (GH-115726)
Instead of showing a dot for each iteration, show:
- '.' for zero (on negative) leaks
- number of leaks for 1-9
- 'X' if there are more leaks
This allows more rapid iteration: when bisecting, I don't need
to wait for the final report to see if the test still leaks.
Also, show the full result if there are any non-zero entries.
This shows negative entries, for the unfortunate cases where
a reference is created and cleaned up in different runs.
Test *failure* is still determined by the existing heuristic.

gh-117187: Fix XML tests for vanilla Expat <2.6.0 (GH-117203)
This fixes XML unittest fallout from the https://github.com/python/cpython/issues/115398 security fix. When configured using `--with-system-expat` on systems with older pre 2.6.0 versions of libexpat, our unittests were failing.
* sax|etree: Simplify Expat version guard where simplifiable
Idea by Matěj Cepl
* sax|etree: Fix reparse deferral tests for vanilla Expat <2.6.0
This *does not fix* the case of distros with an older version of libexpat with the 2.6.0 feature backported as a security fix. (Ubuntu is a known example of this with its libexpat1 2.5.0-2ubunutu0.1 package)
