Prepare for replacement of modified version used in input_server addons. Adapt existing callers. The "this" argument is required, and the CALLED macro can only set it to one single value for an entire file currently. So, in any case where at least one standalone function or static method uses CALLED, the macro has to use a NULL pointer for all calls.
