- Removed the function number parameter from all kernel functions, as it's no longer needed, and removed the FAKE_FUNCT_NR hack
- Removed kUnknown() and kStub()
- Dummy/unknown kernel functions are no longer invoked, and a warning is shown instead, with the paremeters passed to them
Note: there is an evil hack used for debugging scripts in invoke_selector(), which probably no longer works now
