* stage2/asm.S (set_int13_handler): Don't use MBI to get the
lower memory size. Instead, decrease it in the BIOS memory
directly and set %eax to it, since MBI.MEM_LOWER may not be the
same as [0x413] any longer due to the previous change.
* grub/asmstub.c (CONVENTIONAL_MEMSIZE): Changed to 640 * 1024
from 640. You didn't like the inconsistency between
EXTENDED_MEMSIZE and CONVENTIONAL_MEMSIZE, did you?
(get_memsize): Return CONVENTIONAL_MEMSIZE >> 10 instead of
CONVENTIONAL_MEMSIZE, if TYPE is zero.
(get_eisamemsize): Return EXTENDED_MEMSIZE >> 10 instead of
EXTENDED_MEMSIZE / 1024. Just a cosmetic change.
(MMAR_DESC_LENGTH): New macro. Defined as 20.
(get_mmap_entry): Define a new variable DESC_TABLE statically,
and copy the CONTth entry to *DESC if CONT is a correct index.

* stage2/common.c (mmap_avail_at): New function, abstracted out
of init_bios_info, to scan E820 memory map.
(init_bios_info): Use mmap_avail_at for _both_ MBI.MEM_UPPER and
MBI.MEM_LOWER.
