validate_ipv4_address() was affected only on Python < 3.9.5, see [1].
URLValidator() uses a regular expressions and it was affected on all
Python versions.

- Validate filename returned by FileField.upload_to() not a filename
passed to the FileField.generate_filename() (upload_to() may
completely ignored passed filename).
- Allow relative paths (without dot segments) in the generated filename.
Thanks to Jakub Kleň for the report and review.
Thanks to all folks for checking this patch on existing projects.
Thanks Florian Apolloner and Markus Holtermann for the discussion and

In Python 3.9.5+ urllib.parse() automatically removes ASCII newlines
and tabs from URLs [1, 2]. Unfortunately it created an issue in
the URLValidator. URLValidator uses urllib.urlsplit() and
urllib.urlunsplit() for creating a URL variant with Punycode which no
longer contains newlines and tabs in Python 3.9.5+. As a consequence,
the regular expression matched the URL (without unsafe characters) and
the source value (with unsafe characters) was considered valid.

Backport of e1e81aa1c4427411e3c68facdd761229ffea6f6f from main.
The validate_file_name() sanitation introduced in
0b79eb36915d178aef5c6a7bbce71b1e76d376d3 correctly rejects the example
file name as containing path elements on Windows. This breaks the test
introduced in 914c72be2abb1c6dd860cb9279beaa66409ae1b2 to allow path
components for storages that may allow them.
Test is skipped pending a discussed storage refactoring to support this
use-case.

This patch uses a message that causes an xgettext warning regardless of
the version.

Fixed sending emails crash on email addresses with display names longer
then 75 chars on Python 3.6.11+, 3.7.8+, and 3.8.4+.
Wrapped display names were passed to email.headerregistry.Address()
what caused raising an exception because address parts cannot contain
CR or LF.
