Since Emacs 27 the package cl is deprecated, the replacement is cl-lib, which is available since Emacs 24.3. This patch replaces cl by cl-lib and drops support for Emacs versions less than 24.3. Dropping older Emacsen is required, because cl-lib is a builtin starting from version 24.3 and doesn't need an extra package from ELPA. Testcases for past issues still contain cl. Most of them seem to be broken and need further investigation. This patch is tested with test/run-ert.sh, which outputs: Ran 10 tests, 10 results as expected, 0 unexpected (2021-01-30 13:24:54+0100, 0.672122 sec) 1 expected failures and manually by daily usage for a month now.
