* Add yanix crate This commit adds `yanix` crate as a Unix dependency for `wasi-common`. `yanix` stands for Yet Another Nix crate and is exactly what the name suggests: a crate in the spirit of the `nix` crate, but which takes a different approach, using lower-level interfaces with less abstraction, so that it fits better with its main use case, implementation of WASI syscalls. * Replace nix with yanix crate Having introduced `yanix` crate as an in-house replacement for the `nix` crate, this commit makes the necessary changes to `wasi-common` to depend _only_ on `yanix` crate. * Address review comments * make `fd_dup` unsafe * rename `get_fd` to `get_fd_flags`, etc. * reuse `io::Error::last_os_error()` to get the last errno value * Address more comments * make all `fcntl` fns unsafe * adjust `wasi-common` impl appropriately * Make all fns operating on RawFd unsafe * Fix linux build * Address more comments
