* Begin sketching out a new high-level `fs` API. This is a very preliminary sketch of #83. It doesn't even compile yet, but it shows a possible high-level structure of such an API. * Stub out more functionality. * Switch from a lazy_static WasiCtx to a borrowed one. * Reformat some comments. * Code-quote `Self`. * Implement error translation for Windows. * Calls to `fd_close` are now unsafe. * Implement a few more functions.
