We've talked about this many times in the past, but partners struggle to understand "expected 38, got 22" in these contexts, and I always have to go and check the header files just to be sure I'm sure. I actually think the glibc geterrorname_np() function (which would return "ENOSYS" rather than "Function not implemented") would be more helpful, but I'll have to go and implement that first, and then come back. Being forced to go through all our errno assertions did also make me want to use a more consistent style for our ENOSYS assertions in particular --- there's a particularly readable idiom, and I'll also come back and move more of those checks to the most readable idiom. I've added a few missing `errno = 0`s before tests, and removed a few stray `errno = 0`s from tests that don't actually make assertions about errno, since I had to look at every single reference to errno anyway.
