Some notable changes: - `ENOENT` is returned instead of `ENOTCAPABLE` when a path has not be pre-opened (https://github.com/WebAssembly/wasi-libc/pull/370) - `fd_readdir()`: some implementations may not set the inode number, so an additional call to `fstatat()` is now done in order to get it when that happens.
