* Use rsix to make system calls in Wasmtime. `rsix` is a system call wrapper crate that we use in `wasi-common`, which can provide the following advantages in the rest of Wasmtime: - It eliminates some `unsafe` blocks in Wasmtime's code. There's still an `unsafe` block in the library, but this way, the `unsafe` is factored out and clearly scoped. - And, it makes error handling more consistent, factoring out code for checking return values and `io::Error::last_os_error()`, and code that does `errno::set_errno(0)`. This doesn't cover *all* system calls; `rsix` doesn't implement signal-handling APIs, and this doesn't cover calls made through `std` or crates like `userfaultfd`, `rand`, and `region`.
