* Make wasi-common-std-sync's dependency on system-interface private. Change some `pub` functions which exposed system-interface types to be non-`pub`. And, change `from_sysif_fdflags` functions to `get_fd_flags` functions that take `impl AsFilelike` arguments instead of system-interface types. With these changes, system-interface is no longer exposed in the public API. * Add a public API for `is_read_write` too. Implementors using types implementing `AsFilelike` may want to use the same `is_read_write` logic, without explicitly depending on system-interface, so provide a function that provides that.
WASI implementation in Rust, using cap-std.
