Fix sparse file tests of test_tarfile on ppc64le with the tmpfs
filesystem.
Fix the function testing if the filesystem supports sparse files:
create a file which contains data and "holes", instead of creating a
file which contains no data.
tmpfs effective block size is a page size (tmpfs lives in the page
cache). RHEL uses 64 KiB pages on aarch64, ppc64 and ppc64le, only
s390x and x86_64 use 4 KiB pages, whereas the test punch holes of
4 KiB.
test.pythoninfo: Add resource.getpagesize().
It previously deleted Window => Zoom Height by mistake.
(Zoom Height is now on the Options menu). On Mac, the settings
dialog is accessed via Preferences on the IDLE menu.
Make ssl tests less strict and also accept TLSv1 as system default. The
changes unbreaks test_min_max_version on Fedora 29.

Typo fix for method doc, I'm pretty sure coro is meant, because there's no consumer threads for thread-unsafe queue.
Most probably this piece of doc was copied from `queue.Queue`
There's not BPO bug for this, afaik.
While the introduction of ModuleNotFoundError was fully backwards
compatible on the import API consumer side, folks providing alternative
implementations of `__import__` need to make an update to be
forward compatible with clients that start relying on the new subclass.

The subprocess module can now use the os.posix_spawn() function
in some cases for better performance. Currently, it is only used on macOS
and Linux (using glibc 2.24 or newer) if all these conditions are met:
* executable path contains a directory
* close_fds=False
* preexec_fn, pass_fds, cwd, stdin, stdout, stderr
and start_new_session parameters are not set

Fix a NULL pointer deref in ssl module. The cert parser did not handle CRL
distribution points with empty DP or URI correctly. A malicious or buggy
certificate can result into segfault.

asyncio.ProactorEventLoop now catchs and logs send errors when the
self-pipe is full: BaseProactorEventLoop._write_to_self() now catchs
and logs OSError exceptions, as done by
BaseSelectorEventLoop._write_to_self().
IocpProactor.close() now uses time to decide when to log: wait 1
second before the first log, then log every second. Log also the
number of seconds since close() was called.
Previously, calling the strftime() method on a datetime object with a
trailing '%' in the format string would result in an exception. However,
this only occured when the datetime C module was being used; the python
implementation did not match this behavior. Datetime is now PEP-399
compliant, and will not throw an exception on a trailing '%'.
Format characters "%s" and "%V" in PyUnicode_FromFormat() and "%s" in PyBytes_FromFormat()
no longer read memory past the limit if precision is specified.
Use the fast call convention for math functions atan2(),
copysign(), hypot() and remainder() and inline unpacking
arguments. This sped up them by 1.3--2.5 times.
This change separates the signal handling trigger in the eval loop from the "pending calls" machinery. There is no semantic change and the difference in performance is insignificant.
The change makes both components less confusing. It also eliminates the risk of changes to the pending calls affecting signal handling. This is particularly relevant for some upcoming pending calls changes I have in the works.
Use _PyArg_CheckPositional() and inlined code instead of
PyArg_UnpackTuple() and _PyArg_UnpackStack() if all parameters
are positional and use the "object" converter.
