* Finally bring syscall.h up to speed and include all syscalls in the syscall module of the C library. * Remove the third-party obfuscated C demos (we have nyancat, good enough) * Fix userspace apps to build without complaining about undeclared strtok_r by disable __STRICT_ANSI__ * Fix .eh_frame by including the proper stuff with libgcc.
