[ion] 22264: - Clone ObpCreateHandle to CmpCreateHandle. I am about to fix its implementation and since Cm* currently abuses Ob I feel it safer to give its own internal function. - Make ObpCreateHandle internal to Ob as it should be. Change NtCreateProcessTokenEx to use ObOpenObjectByPointer, it has no business manually trying to create a handle. Same goes for ExpLoadInitialProcess.
