As a side effect from adding explicit license files to conform to PEP 639, the
AUTHORS file got dropped from the wheel. The tarball still contained this file.

In the "Python Packaging User Guide"
(https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license-files)
the AUTHORS file is modeled to be included in license-files.

This simplicaftion mitigates a potential DoS in URLField on Windows. The
usage of `urlsplit()` in `URLField.to_python()` was replaced with
`str.partition(":")` for URL scheme detection. On Windows, `urlsplit()`
performs Unicode normalization which is slow for certain characters,
making `URLField` vulnerable to DoS via specially crafted POST payloads.

Thanks Seokchan Yoon for the report, and Jake Howard and Shai Berger
for the review.

…ssions on file system object creation.

This fix introduces `safe_makedirs()` in the `os` utils as a safer
alternative to `os.makedirs()` that avoids umask-related race conditions
in multi-threaded environments.

This is a workaround for python/cpython#86533
and the solution is based on the fix being proposed for CPython.
