[3.8] bpo-37409: fix relative import with no parent (GH-14956) (GH-15913)
Relative imports use resolve_name to get the absolute target name,
which first seeks the current module's absolute package name from the globals:
If __package__ (and __spec__.parent) are missing then
import uses __name__, truncating the last segment if
the module is a submodule rather than a package __init__.py
(which it guesses from whether __path__ is defined).
The __name__ attempt should fail if there is no parent package (top level modules),
if __name__ is '__main__' (-m entry points), or both (scripts).
That is, if both __name__ has no subcomponents and the module does not seem
to be a package __init__ module then import should fail..

bpo-35066: Make trailing percent test more portable. (GH-15907)
Different libc implementations have different behavior when presented with trailing % in strftime strings. To make test_strftime_trailing_percent more portable, compare the output of datetime.strftime directly to that of time.strftime rather than hardcoding.

bpo-37424: Avoid a hang in subprocess.run timeout output capture (GH-14490)
Fixes a possible hang when using a timeout on subprocess.run() while
capturing output. If the child process spawned its own children or otherwise
connected its stdout or stderr handles with another process, we could hang
after the timeout was reached and our child was killed when attempting to read
final output from the pipes.

bpo-37936: Avoid ignoring files that we actually do track. (GH-15451) (GH-15748)
There were about 14 files that are actually in the repo but that are
covered by the rules in .gitignore.
Git itself takes no notice of what .gitignore says about files that
it's already tracking... but the discrepancy can be confusing to a
human that adds a new file unexpectedly covered by these rules, as
well as to non-Git software that looks at .gitignore but doesn't
implement this wrinkle in its semantics. (E.g., `rg`.)
Several of these are from rules that apply more broadly than
intended: for example, `Makefile` applies to `Doc/Makefile` and
`Tools/freeze/test/Makefile`, whereas `/Makefile` means only the
`Makefile` at the repo's root.

bpo-37380: subprocess: don't use _active on win (GH-14360) (GH-15706)
As noted by @eryksun in [1] and [2], using _cleanup and _active(in
__del__) is not necessary on Windows, since:
> Unlike Unix, a process in Windows doesn't have to be waited on by
> its parent to avoid a zombie. Keeping the handle open will actually
> create a zombie until the next _cleanup() call, which may be never
> if Popen() isn't called again.
This patch simply defines `subprocess._active` as `None`, for which we already
have the proper logic in place in `subprocess.Popen.__del__`, that prevents it
from trying to append the process to the `_active`. This patch also defines
`subprocess._cleanup` as a noop for Windows.

bpo-37936: Remove some .gitignore rules that were intended locally. (GH-15542)
These appeared in commit c5ae169e1. The comment on them, as well as
the presence among them of a rule for the .gitignore file itself,
indicate that the author intended these lines to remain only in their
own local working tree -- not to get committed even to their own repo,
let alone merged upstream.
They did nevertheless get committed, because it turns out that Git
takes no notice of what .gitignore says about files that it's already
tracking... for example, this .gitignore file itself.
Give effect to these lines' original intention, by deleting them. :-)
Git tip, for reference: the `.git/info/exclude` file is a handy way
to do exactly what these lines were originally intended to do. A
related handy file is `~/.config/git/ignore`. See gitignore(5),
aka `git help ignore`, for details.
These were caused by keeping around a reference to the Squeezer
instance and calling it's load_font() upon config changes, which
sometimes happened even if the shell window no longer existed.
This change completely removes that mechanism, instead having the
editor window properly update its width attribute, which can then
be used by Squeezer.
