Bug 299752: textproc/py-humanfriendly: Replace pipes with shlex for Python 3.13
(humanfriendly.cli fails to import)
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=299752



--- Description ---
humanfriendly.cli, the module behind the humanfriendly console script,
fails to import on Python 3.13:

    $ python3.13 -c 'import humanfriendly.cli'
    ModuleNotFoundError: No module named 'pipes'

humanfriendly/cli.py and humanfriendly/testing.py do `import pipes` and
use pipes.quote. The pipes module was removed in Python 3.13. The
library API (format_size, parse_*, terminal, ...) does not import
either module and is not affected.

The patch replaces pipes.quote with shlex.quote in cli.py and
testing.py and bumps PORTREVISION.

Misc changes:
- the port switches to USE_PYTHON=pep517 (the package metadata becomes
  dist-info)
- the patches in files/ get a header saying what each one does and its
  upstream status (Description, Issue ID, Changeset, TODO)

Impact: 17 ports depend on py-humanfriendly; they use the library API,
and none of them needs a change.

Tested: poudriere bulk on amd64, both with Python 3.12 and with
DEFAULT_VERSIONS+=python=3.13, after the pep517 switch: builds, installs
the package metadata as .dist-info, and the modules import from the
built package (only optional extras are missing).

Upstream: 10.0 (2021-09-17) is the latest release and the project is
unmaintained; GitHub master still imports pipes.
