Ben Gras d65f6f7009 imported code harmonisation
. common/include/arch/i386 is not actually an imported
	  sys/arch/i386/include but leftover Minix files;
	  remove and move to include/
	. move include/ufs to sys/ufs, where it came from, now that
	  we have a sys/ hierarchy
	. move mdocml/ to external/bsd/, now we have that
	. single sys/arch/i386/stand/ import for boot stuff
