If __stdout__ is not attached to terminal, try to use __stderr__
if it is attached to terminal, or open the terminal device, or
use regular file as terminal, but some functions will be untested
in the latter case.

It did not work because the signature of code object constructor
was changed. Also, it used old format of bytecode (pre-wordcode).

When the modern text= spelling of the universal_newlines= parameter was added
for Python 3.7, check_output's special case around input=None was overlooked.
So it behaved differently with universal_newlines=True vs text=True. This
reconciles the behavior to be consistent and adds a test to guarantee it.
Also clarifies the existing check_output documentation.

Added `__getitem__` for `_CallableGenericAlias` so that it returns a subclass (itself) of `types.GenericAlias` rather than the default behavior of returning a plain `types.GenericAlias`. This fixes `repr` issues occuring after `TypeVar` substitution arising from the previous behavior.

* bpo-42644: Validate values in logging.disable()
Technically make the value of manager a property that checks and convert
values assigned to it properly. This has the side effect of making
`logging.disable` also accept strings representing the various level of
warnings.
We want to validate the type of the disable attribute at assignment
time, as it is later compared to other levels when emitting warnings and
would generate a `TypeError: '>=' not supported between ....` in a
different part of the code base, which can make it difficult to track
down.
When assigned an incorrect value; it will raise a TypeError when the
wrong type, or ValueError if an invalid str.

When creating an Enum, `type.__new__` calls `__init_subclass__`, but at that point the members have not been added.
This patch suppresses the initial call, then manually calls the ancestor `__init_subclass__` before returning the new Enum class.

Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:
- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip
Previously, they could have become untracked by a prior garbage collection.

Use `_PyArg_NoKeywords` instead of `_PyArg_NoKwnames` when checking the `kwds` tuple when creating `GenericAlias`. This fixes an interpreter crash when passing in keyword arguments to `GenericAlias`'s constructor.
Needs backport to 3.9.

macOS releases numbering has changed as of macOS 11 Big Sur. Previously, major releases were of the form 10.x, 10.x+1, 10.x+2, etc; as of Big Sur, they are now x, x+1, etc, so, for example, 10.15, 10.15.1, ..., 10.15.7, 11, 11.0.1, 11.1, ..., 12, 12.1, etc. Allow Python to build with single-digit deployment target values. Patch provided by FX Coudert.

* [3.9] bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)
Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com>
* Add support for macOS 11 and Apple Silicon (aka arm64)
As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy
* Support building on recent versions of macOS while deploying to older versions
This allows building installers on macOS 11 while still supporting macOS 10.9..

send_signal() now swallows the exception if the process it thought was still alive winds up not to exist anymore (always a plausible race condition despite the checks).
