Wrap access to errno, for use in the block layer and character device bindings.
Supersedes: <20250212093958.3703269-1-pbonz...@redhat.com> v1->v2: - use the libc crate - provide separate From<Errno> implementation for io::ErrorKind - hide GetErrno trait inside a submodule - add into_neg_errno() and corresponding tests - add more doctests - make Errno field public, so that Errno can have other From<...> implementations (e.g. going from *mut Error to Errno).
