Update configure since configure.ac was modified to drop support for
FreeBSD 4.

PyUnicode_DecodeLocaleAndSize(), PyUnicode_DecodeLocale() and
PyUnicode_EncodeLocale() now use always use the UTF-8 encoding on
Android, instead of the current locale encoding.

On Android API 19, mbstowcs() and wcstombs() are broken and cannot be
used.

Drop support of FreeBSD 9 and older.

* bpo-31801:  Enum:  add _ignore_ as class option

_ignore_ is a list, or white-space seperated str, of names that will not
be candidates for members; these names, and _ignore_ itself, are removed
from the final class.

* bpo-31801:  Enum:  add documentation for _ignore_

* bpo-31801: Enum: remove trailing whitespace

* bpo-31801: Enum: fix bulleted list format

* bpo-31801: add version added for _ignore_

The previous version was correct in terms of behaviour, but
checking the return value of PyErr_WarnFormat allows to
avoid calling PyErr_Occurred and silences the coverity alarm.

* Add coro.cr_origin and sys.set_coroutine_origin_tracking_depth
* Use coroutine origin information in the unawaited coroutine warning
* Stop using set_coroutine_wrapper in asyncio debug mode
* In BaseEventLoop.set_debug, enable debugging in the correct thread

Add test certs and test for ECDSA cert and EC/RSA dual mode.

I'm also adding certs for IDNA 2003/2008 tests and simplify some test
data handling.

Add https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html
to auto-detect compiler flags, linker flags and libraries to compile
OpenSSL extensions. The M4 macro uses pkg-config and falls back to
manual detection.

Add autoconf magic to detect usable X509_VERIFY_PARAM_set1_host()
and related functions.

Refactor setup.py to use new config vars to compile _ssl and _hashlib
modules.

This PR re-designs the internal typing API using the new PEP 560 features.
However, there are only few minor changes in the public API.

The suggested replacement for print statements previously failed to account
for leading whitespace and hence could end up including unwanted text in
the proposed call to the print builtin.

Patch by Sanyam Khurana.

Fixes some redirection links in docs.

* Use wider types (int => Py_ssize_t) to avoid integer overflows.
* Fix gc.get_freeze_count(): use Py_ssize_t type rather than int, since gc_list_size() returns a Py_ssize_t.

Where a queue may be invoked from a weakref callback, we need
to use the reentrant SimpleQueue.

The comment for PyThread_allocate_lock says "It has too be implemented ...".
There was an extra "o" in ".. to be implemented.."

This test doesn't care about order, the underlying filesystem APIs do not
guarantee directory listings on subsequent calls will be in the same order.

Use the binary.file instead of utf-8.file to avoid issues with
Unix newlines vs Windows newlines.

bpo-32248: Make sure that Git checks out data files with Unix line
ending on Windows as well.

Use an improved version of multissl test helper to compile a local copy
of OpenSSL 1.1.0g.

* Add tests for date subclass alternate constructors

* Switch over alternate date constructors to fast path

* Switch datetime constructors to fastpath, fix bpo-32404

* Add fast path for datetime in date subclass constructor

* Set fold in constructor in datetime.combine

* Add news entries.

bpo-29240: On FreeBSD, if the LC_CTYPE locale is "C" or "POSIX",
writing and reading non-ASCII bytes into/from a TTY works,
but readline or ncurses ignores non-ASCII bytes on read.

AttributeError was raised always when attribute is not found.
This commit skip raising AttributeError when `tp_getattro` is `PyObject_GenericGetAttr`.
It makes hasattr() and getattr() about 4x faster when attribute is not found.

Add a queue.SimpleQueue class, an unbounded FIFO queue with a reentrant C implementation of put().
