inline functions being declared in two source files - ym2413.c and
ym2612.c. A call to set_sl_rr in ym2612.c would jump to the inline
function declared in ym2413.c and completely crashihng the app.
Both functions in the input files have now been uniquely named to
avoid conflicts. There might be more conflicts up ahead (sound is still
not correct), but at least games run now
