Unlikely errors in preparing arguments for ctypes callback are now
handled in the same way as errors raised in the callback of in converting
the result of the callback -- using sys.unraisablehook() instead of
sys.excepthook() and not setting sys.last_exc and other variables.
Implement PyUnicode_KIND() and PyUnicode_DATA() as function, in
addition to the macros with the same names. The macros rely on C bit
fields which have compiler-specific layout.
Slicing buf and appending chunk would always result in a copy. Commonly
in a readall() there is no already read data in buf, and the amount of
data read may be large, so the copy is expensive.
Both now use a pre-allocated buffer of length `bufsize`, fill it using
a readinto(), and have matching "expand buffer" logic.
On my machine this takes:
`./python -m test -M8g -uall test_largefile -m test_large_read -v`
from ~3.7 seconds to ~3.4 seconds.
This exposes `_Py_TryIncref` as `PyUnstable_TryIncref()` and the helper
function `_PyObject_SetMaybeWeakref` as `PyUnstable_EnableTryIncRef`.
These are helpers for dealing with unowned references in a safe way,
particularly in the free threading build.

`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.
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()`.
