	i have no partuclar preference, other than:
	- when we share *.h from multiple *.c, the function signature
	  must be unified - like sys/lib/libsa/stand.h.
	- if we unify, exit(int) should be more useful than exit(void),
	  as there may be some party would like to use return value for some
	  purpose.

	i386 falled into the former case, so i unfieid all i386 bootloader
	to exit(int).  for other ports, it is really up to portmasters.
