Module std::errno

The errno std::fs, std::net and std::env answer in their Errs, named and formatted. They answer the kernel's word, a bare Int, so a match takes Err(2); wrapping it, Errno::new(e), gives its Display: strerror's text as glibc words it (No such file or directory), and Unknown error <n> for a number outside the table.
