Started this when writing tests for a feature I'm working on, needing a way to
read/write numbers to system files. 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.
V3: * Add reviewed-by from previous version
* Fix write(2) call to include creation mode
