move sys fns into c-stack-cdecl and get_type_desc() into rusti
there is one test failure, stdtest/sys.rs, which inexplicably (thus far) fails to compile because it invokes sys::rustrt::last_os_error() instead of invoking sys::last_os_error(). If stdtest/sys.rs is updated to invoke the wrapper, it passes. Still tracing the source of this error.
