Remove interp_ui_out

The function interp_ui_out simply calls the interp_ui_out method.
However, if it is passed a NULL interpreter, it first finds the
current interpreter.  I believe, though, that NULL is never passed
here, and I think it's simpler to just remove this function and
require callers to be more explicit.
