* licensing: add spdx to our .cocci filesZbigniew Jędrzejewski-Szmek2021-10-011-0/+1

* util: add new safe_close_above_stdio() wrapperLennart Poettering2018-02-281-0/+36
At various places we only want to close fds if they are not stdin/stdout/stderr, i.e. fds 0, 1, 2. Let's add a unified helper call for that, and port everything over.
