Change magnum types to match other platforms (#525)

Improve system call wrappers This change improves copy_file_range(), sendfile(), splice(), openpty(), closefrom(), close_range(), fadvise() and posix_fadvise() in addition to writing tests that confirm things like errno and seeking behavior across platforms. We now less aggressively polyfill behavior with some of these functions when the platform support isn't available. Please see: https://justine.lol/cosmopolitan/functions.html

Explore comfort level with posix_spawn Justine says nay for the time being. Only XNU implements this. It's not clear what ABI XNU is using but it's obviously not the one in the POSIX documentation link below. Since all platforms implement vfork, it might be better to empirically gauge the intersection of consensus which will have better performance than this interface. https://pubs.opengroup.org/onlinepubs/009696699/xrat/xsh_chap03.html
