* Reuse std::io::Error for raw *nix errno This commit removes custom `yanix::Errno` and instead (as was previously suggested) reuses `std::io::Error` to generate and wrap raw *nix errno value. * Update wasi-common to use new Yanix error type This commit updates `wasi-common` to use new way of handling raw OS error in `yanix`; i.e., via re-use of `std::io::Error` instead of a custom `Errno` enum. * Fix formatting * Unwrap if io::Error created from raw OS error This commit calls `unwrap` on `err` if that one was created via `io::Error::last_os_error()`. It also refactors error matching in several syscalls on the BSD platform (mainly).
