Define the behavior of the boot loader when the load end address
	and the bss end address are zero in the Multiboot Specification,
	and add the support into GRUB. I've modified a patch from Yuri
	Zaporogets <yuriz@ukr.net>.

	* stage2/boot.c (load_image): In the case of Multiboot a.out
	kludge, set the load end address to the load address plus the
	size of the OS image file, if it is zero. Similarly, set the bss
	end address to the load end address, if it is zero.

	* util/mbchk.c (check_multiboot): Don't check if the load
	address is greater than or equal to the load end address, if the
	load end address is zero. Don't check if the load end address is
	greater than the bss end address, if the bss end address is
	zero. And, don't check if the load end address is less than or
	equal to the entry address, if the load end address is zero.

	* docs/multiboot.texi (The address fields of Multiboot header):
	Added descriptions about the behavior of the boot loader when
	LOAD_END_ADDR is zero and BSS_END_ADDR is zero.
