rust: add module to convert between success/-errno and io::Result
It is a common convention in QEMU to return a positive value in case of
success, and a negated errno value in case of error. Unfortunately,
using errno portably in Rust is a bit complicated; on Unix the errno
values are supported natively by io::Error, but on Windows they are not;
so, use the libc crate.
This is a set of utility functions that are used by both chardev and
block layer bindings.
