* remove type annotations from multiprocessing.
One of them was technically invalid per typing specs... but since we're not
checking these in the stdlib today lets elide them.
https://discuss.python.org/t/static-type-annotations-in-cpython/65068/13
* use the actual comment style annotation format

The `dict.get` implementation uses `_Py_dict_lookup_threadsafe`, which is
thread-safe, so we remove the critical section from the argument clinic.
Add a test for concurrent dict get and set operations.
Unlike `ReadablePath.[r]glob()` and `JoinablePath.full_match()`, the
`JoinablePath.match()` method doesn't support the recursive wildcard `**`,
and matches from the right when a fully relative pattern is given. These
quirks means its probably unsuitable for inclusion in the pathlib ABCs,
especially given `full_match()` handles the same use case.
`os.read()` allocated and filled a buffer by calling `read(2)`, than that
data was copied into the user provied buffer. Read directly into the
caller's buffer instead by using `os.readinto()`.
`os.readinto()` uses `PyObject_GetBuffer()` to make sure the passed
in buffer is writeable and bytes-like, drop the manual check.
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.
This reduces the size of _PyInterpreterFrame by 8 bytes on 64-bit
platforms using the free threading build due to alignment requirements.
This allows for slightly more recursive calls into the interpreter (from
C), but `test_call.test_super_deep` still crashes.
* Remove all 'if (0)' and 'if (1)' conditional stack effects
* Use array instead of conditional for BUILD_SLICE args
* Refactor LOAD_GLOBAL to use a common conditional uop
* Remove conditional stack effects from LOAD_ATTR specializations
* Replace conditional stack effects in LOAD_ATTR with a 0 or 1 sized array.
* Remove conditional stack effects from CALL_FUNCTION_EX
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.

Ignore PermissionError when checking cwd during import
On macOS `getcwd(3)` can return EACCES if a path component isn't readable,
resulting in PermissionError. `PathFinder.find_spec()` now catches these and
ignores them - the same treatment as a missing/deleted cwd.
Introduces `test.support.os_helper.save_mode(path, ...)`, a context manager
that restores the mode of a path on exit.
This is allows finer control of exception handling and robust environment
restoration across platforms in `FinderTests.test_permission_error_cwd()`.

We remove the safeguards that were added in `Lib/test/test_capi/test_codecs.py`
since they are now redundant (see 32e07fd377
for additional context).
Indeed, the codecs handlers now correctly handle the `start` and `end` positions
of `UnicodeError` objects and thus should not crash.
This adds basic support to override default messages for domain errors
in the math_1() helper. The sqrt(), atanh(), log2(), log10() and log()
functions were modified as examples. New macro supports gradual
changing of error messages in other 1-arg functions.

This fixes how `PyCodec_BackslashReplaceErrors` handles the `start` and `end`
attributes of `UnicodeError` objects via the `_PyUnicodeError_GetParams` helper.
Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack()
during late Python finalization.
* Call _PyTraceMalloc_Fini() later in Python finalization.
* Test also PyTraceMalloc_Untrack() without the GIL
* PyTraceMalloc_Untrack() now gets the GIL.
* Test also PyTraceMalloc_Untrack() in test_tracemalloc_track_race().
