On non-Linux POSIX platforms, like FreeBSD or macOS,
the FD used to read a forked PTY may signal its exit not
by raising an error but by sending empty data to the read
syscall. This case wasn't handled, leading to hanging
`pty.spawn` calls.

* Refactor dispatch logic to make flow of control clearer. Moves lltrace and dxprofile instrumentation into DISPATCH macro.
* Remove switch in interpreter loop when using computed gotos. There is no need for two nearly-duplicate dispatch tables.
This was causing test___all__ to fail on platforms lacking a shared
memory implementation.

* Generalize cache names for LOAD_ATTR to allow store and delete specializations.
* Factor out specialization of attribute dictionary access.
* Specialize STORE_ATTR.
* MemoryError is now raised instead of sqlite3.Warning when
memory is not enough for encoding a statement to UTF-8
in Connection.__call__() and Cursor.execute().
* UnicodEncodeError is now raised instead of sqlite3.Warning when
the statement contains surrogate characters
in Connection.__call__() and Cursor.execute().
* TypeError is now raised instead of ValueError for non-string
script argument in Cursor.executescript().
* ValueError is now raised for script containing the null
character instead of truncating it in Cursor.executescript().
* Correctly handle exceptions raised when getting boolean value
of the result of the progress handler.
* Add many tests covering different corner cases.

MemoryError raised in user-defined functions will now preserve
its type. OverflowError will now be converted to DataError.
Previously both were converted to OperationalError.
Fix the os.set_inheritable() function on FreeBSD 14 for file
descriptor opened with the O_PATH flag: ignore the EBADF error on
ioctl(), fallback on the fcntl() implementation.
* When trying to allocate very large regions on macOS, malloc does not fail silently. It sends a noisy error out to STDERR
* This provides a helper function to warn the user, and provides the warning for test_decimal, which consistently generates these warnings on macOS.

The threading debug (PYTHONTHREADDEBUG environment variable) is
deprecated in Python 3.10 and will be removed in Python 3.12. This
feature requires a debug build of Python.
* Unify the C and Python implementations of OrderedDict.popitem().
The C implementation no longer calls ``__getitem__`` and ``__delitem__``
methods of the OrderedDict subclasses.
* Change popitem() and pop() methods of collections.OrderedDict
For consistency with dict both implementations (pure Python and C)
of these methods in OrderedDict no longer call __getitem__ and
__delitem__ methods of the OrderedDict subclasses.
Previously only the Python implementation of popitem() did not
call them.
For example Callable[P, T][[int], str, float] will now raise an error.
Use also term "arguments" instead of "parameters" in error
message for too few/many arguments.
When sys.stdout.encoding is None compile_file will fall back to
sys.getdefaultencoding to encode/decode error messages.
