Remove rubber duck from BRW, RW and most weapon schemes for now The duck is not liked by players. Rubber duck needs a lot of rework. Before that happens, better remove it from game modes for now. Players can always modify the weapon schemes, of course.

void fpcrtl_halt(int num) {
    __coverity_panic__();
}

int fpcrtl_abs(int num) {
    return num >= 0 ? num : -num;
}
