* loader/i386/pc/multiboot.c (playground, forward_relocator)
        (backward_relocator): New variables.  Used to allocate and relocate
        the payload, respectively.
        (grub_multiboot_load_elf32): Load into heap instead of requested
        address, install the appropiate relocator code in each bound of
        the payload, and set the entry point such that
        grub_multiboot_real_boot() will jump to one of them.

        * kern/i386/loader.S (grub_multiboot_payload_size)
        (grub_multiboot_payload_orig, grub_multiboot_payload_dest)
        (grub_multiboot_payload_entry_offset): New variables.
        (grub_multiboot_real_boot): Set cpu context to what the relocator
        expects, and jump to the relocator instead of the payload.

        * include/grub/i386/loader.h (grub_multiboot_payload_size)
        (grub_multiboot_payload_orig, grub_multiboot_payload_dest)
        (grub_multiboot_payload_entry_offset): Export.
