man: recommend strerror_r() over strerror()
Let's nudge people towards the use of an anonymous buffer like we
do internally.
"errno" → "errnum", to match the man page for strerror, and also to avoid
confusion with the global variable. In general, I think that errno is a
terrible interface and we shouldn't encourage people to use it. Those functions
use errno-style error numbers, which are a different thing.
