syscall emulation: Clean up ioctl handling, and implement for x86.
Enable different whitelists for different OS/arch combinations, since some use the generic Linux definitions only, and others use definitions inherited from earlier Unix flavors on those architectures. Also update x86 function pointers so ioctl is no longer unimplemented on that platform. This patch is a revised version of Vince Weaver's earlier patch.
