rework treatment of native functions (and there's not even a native
function to test yet)
Native functions are now executed in swfdec_context_run.
This makes sure all execution is done in swfdec_context_run. This allows:
- better debugging hooks, since it's only one function.
- less error cases of which function does what to the current frame.
Also new is that frames now reference the function they execute
