Move them into per-instance structs. This should get rid of all global variables in mplayer.c (not counting those referenced by cfg-mplayer.h). In core/input/ar.c, just remove checking the slave_mode variable. I'm not sure what this code was supposed to achieve, but slave mode is broken, slave mode is actually infeasible on OSX (ar.c is completely OSX specific), and the correct way of doing this would be to disable this input device per command line switch.
