After writing some utils to safely handle file IO and parsing, I realised I'd made the ~6th file read/write implementation and only(?) number parser that checks all the failure modes when expecting to parse a single number from a file. So these utils ended up becoming this series. I also modified some other test utils I came across while doing so. My understanding is selftests are not expected to be backported, so I wasn't concerned about only introducing new utils and leaving the existing implementations be.
