The CPython uses _Py_dg_dtoa(), which does rounding to nearest with half
to even tie-breaking rule.
If that functions is unavailable, PyOS_double_to_string() fallbacks to
system snprintf(). Since CPython 3.12, build requirements include C11
compiler *and* support for IEEE 754 floating point numbers (Annex F).
This means that FE_TONEAREST macro is available and, per default,
printf-like functions should use same rounding mode as _Py_dg_dtoa().

gh-123967: Fix faulthandler for trampoline frames (#127329)
If the top-most frame is a trampoline frame, skip it.
(cherry picked from commit 58e334e143)
Since MultiByteToWideChar()/WideCharToMultiByte() is not reversible if
the data contains invalid UTF-8 sequences, use binary search to
calculate the number of written bytes from the number of written
characters.
Also fix writing incomplete UTF-8 sequences.
Also fix handling of memory allocation failures.

Improve `pathname2url()` and `url2pathname()` docs (GH-127125)
These functions have long sown confusion among Python developers. The
existing documentation says they deal with URL path components, but that
doesn't fit the evidence on Windows:
>>> pathname2url(r'C:\foo')
'///C:/foo'
>>> pathname2url(r'\\server\share')
'////server/share' # or '//server/share' as of quite recently
If these were URL path components, they would imply complete URLs like
`file://///C:/foo` and `file://////server/share`. Clearly this isn't right.
Yet the implementation in `nturl2path` is deliberate, and the
`url2pathname()` function correctly inverts it.
On non-Windows platforms, the behaviour until quite recently is to simply
quote/unquote the path without adding or removing any leading slashes. This
behaviour is compatible with *both* interpretations -- 1) the value is a
URL path component (existing docs), and 2) the value is everything
following `file:` (this commit)
The conclusion I draw is that these functions operate on everything after
the `file:` prefix, which may include an authority section. This is the
only explanation that fits both the Windows and non-Windows behaviour.
It's also a better match for the function names.

GH-127078: `url2pathname()`: handle extra slash before UNC drive in URL path (GH-127132)
Decode a file URI like `file://///server/share` as a UNC path like

prepends `file:///` to any absolute Windows path.

GH-85168: Use filesystem encoding when converting to/from `file` URIs (GH-126852)
Adjust `urllib.request.url2pathname()` and `pathname2url()` to use the
filesystem encoding when quoting and unquoting file URIs, rather than
forcing use of UTF-8.
No changes are needed in the `nturl2path` module because Windows always
uses UTF-8, per PEP 529.

Modify the extended attribute tests to write fewer and smaller extended

of 1 KiB (e.g. ext4 with 1 KiB blocks). Previously, the test would
write over 2 KiB, making it fail with ENOSPC on such systems.

gh-124452: Fix header mismatches when folding/unfolding with email message (GH-125919)
The header-folder of the new email API has a long standing known buglet where
if the first token is longer than max_line_length, it puts that token on the next
line. It turns out there is also a *parsing* bug when parsing such a header:
the space prefixing that first, non-empty line gets preserved and tacked on to
the start of the header value, which is not the expected behavior per the RFCs.
The bug arises from the fact that the parser assumed that there would be at
least one token on the line with the header, which is going to be true for
probably every email producer other than the python email library with its
folding buglet. Clearly, though, this is a case that needs to be handled
correctly. The fix is simple: strip the blanks off the start of the whole
value, not just the first physical line of the value.
