This fixes various test issues with Go 1.20. - Most tests rewritten to use fakefs where possible - Some tests that were already skipped, or dubious (invasive, unmaintainable, unclear what they even tested) have been removed - Some actual code rewritten to better support testing in fakefs Co-authored-by: Eric P <eric@kastelo.net>
