gh-130250: use support.swap_attr() in test and don't assume we're beginning with a clean system state (GH-130342)
(cherry picked from commit 048ee2d5ec)
Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>
We had the definition of what makes a character "printable" documented in three places, giving two different definitions.
The definition in the comment on `_PyUnicode_IsPrintable` was inverted; correct that.
With that correction, the two definitions turn out to be equivalent -- but to confirm that, you have to go look up, or happen to know, that those are the only five "Other" categories and only three "Separator" categories in the Unicode character database. That makes it hard for the reader to tell whether they really are the same, or if there's some subtle difference in the intended semantics.
Fix that by cutting the C API docs' and the C comment's copies of the subtle details, in favor of referring to the Python-level docs. That ensures it's explicit that these are all meant to agree, and also lets us concentrate improvements to the wording in one place.
Speaking of which, borrow some ideas from the C comment, along with other tweaks, to hopefully add a bit more clarity to that one newly-centralized copy in the docs.
Also add a thorough test that the implementation agrees with this definition.

Test that the trailing pathname separator is preserved.
Multiple trailing pathname separators are only preserved if the pattern
does not contain metacharacters, otherwise only one trailing pathname
separator is preserved. This is rather an implementation detail.

gh-112064: Fix incorrect handling of negative read sizes in `HTTPResponse.read()` (GH-128270)
The parameter `amt` of `HTTPResponse.read()`, which could be a negative integer,
has not been handled before and led to waiting for the connection to close
for `keep-alive connections`. Now, this has been fixed, and passing negative values
to `HTTPResponse().read()` works the same as passing `None` value.

gh-119511: Fix a potential denial of service in imaplib (GH-119514)
The IMAP4 client could consume an arbitrary amount of memory when trying
to connect to a malicious server, because it read a "literal" data with a
single read(size) call, and BufferedReader.read() allocates the bytes
object of the specified size before reading. Now the IMAP4 client reads data
by chunks, therefore the amount of used memory is limited by the
amount of the data actually been sent by the server.

gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191)
Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack()

gh-80222: Fix email address header folding with long quoted-string (GH-122753)
Email generators using email.policy.default could incorrectly omit the
quote ('"') characters from a quoted-string during header refolding,
leading to invalid address headers and enabling header spoofing. This
change restores the quote characters on a bare-quoted-string as the
header is refolded, and escapes backslash and quote chars in the string.

[3.13] gh-128679: Fix tracemalloc.stop() race conditions (#128897)
tracemalloc_alloc(), tracemalloc_realloc(), PyTraceMalloc_Track(),
PyTraceMalloc_Untrack() and _PyTraceMalloc_TraceRef() now check
tracemalloc_config.tracing after calling TABLES_LOCK().
_PyTraceMalloc_Stop() now protects more code with TABLES_LOCK(),
especially setting tracemalloc_config.tracing to 1.
Add a test using PyTraceMalloc_Track() to test tracemalloc.stop()
race condition.
Call _PyTraceMalloc_Init() at Python startup.
