* conf/i386-pc.rmk (kernel_img_SOURCES): Add `kern/i386/pc/mmap.c'.

        * include/grub/i386/pc/init.h (GRUB_MACHINE_MEMORY_AVAILABLE)
        (GRUB_MACHINE_MEMORY_RESERVED): New macros.
        (grub_machine_mmap_iterate): New function declaration.
        * include/grub/multiboot.h (struct grub_multiboot_mmap_entry): New
        structure.
        (GRUB_MMAP_MEMORY_AVAILABLE, GRUB_MMAP_MEMORY_RESERVED): New
        macros.

        * kern/i386/pc/init.c (grub_machine_init): Replace hardcoded region
        type check value with `GRUB_MACHINE_MEMORY_AVAILABLE'.
        Move e820 parsing from here ...
        * kern/i386/pc/mmap.c: New file.
        (grub_machine_mmap_iterate): ... to here.
