Switch to single intervals for FSF notices,
and consistently put them first.
Update copyright notices for 2024.
* cfg.mk (update-copyright-env): Use UPDATE_COPYRIGHT_FORCE=1,
UPDATE_COPYRIGHT_USE_INTERVALS=2.
* patch.man: Always use \(co, so that update-copyright
updates these dates.
* src/version.c: Correct Larry Wall copyright years.
Since the code is identical when just checking if a utility is present on
the system or not, we can factorize it.

* src/patch.c (main): Say that we are checking a file and not that we are
patching it in --dry-run mode. Don't say "saving rejects to file" when we
don't create reject files.
* tests/reject-format: Add rejects with --dry-run test case.
* tests/bad-filenames, tests/fifo, tests/mixed-patch-types: Update.
* src/pch.c (open_patch_file): Also check if the input file is
seekable if a filename is given (-i).
* tests/pipe: New file. Test this.
* tests/Makefile.am (TESTS): Add it.
