Userland: Add LibSystem and funnel all syscalls through it
This achieves two things: - Programs can now intentionally perform arbitrary syscalls by calling syscall(). This allows us to work on things like syscall fuzzing. - It restricts the ability of userspace to make syscalls to a single 4KB page of code. In order to call the kernel directly, an attacker must now locate this page and call through it.
