Added sforkr(2) that controls the child registers as well. sfork(2) now calls sforkr(2) with the current registers. This will prove useful in creating threads, where user-space now can fully control what state the child will start in. This is unlike the Linux clone system call that accepts a pointer to the child stack; this is more powerful and somehow simpler. Note that this will create a rather raw thread; no thread initization has been done by the standard thread API (when it is implemented), so this feature shouldn't be used by programmers unless they know what they are doing. fork(2) now calls sfork(2) directly. Also removed fork(2) and sfork(2) from the kernel as they are done using sforkr(2) now. So technically they aren't system calls right now, but that could always change.
