Log message:
        This patch is to introduce multiboot 2 loading capabilities to grub2
        for powerpc & i386-pc. This patch was more so started by Hollis
        Blanchard getting multiboot 2 working for powerpc and I added to it
        and cleaned it up.
        One of the ideas with this patch is to keep everything under one
        command for the user. So instead of having a "multiboot2" & "module2"
        command, I created a proxy like mechanism so that you have only one
        command for both multiboot 1 & 2 ... "multiboot". This is where
        "loader/multiboot_loader.c" comes from. I could have integrated things
        more but I figure the current approach will less likely break
        So if your OS is multiboot 2 capable, the user would do the following
        to load it up from a grub prompt:
        grub> multiboot <location of kernel> <kernel args>
        grub> module <some image> <multiboot tag> <image arguments>
        grub> module <isome mage> <multiboot tag> <image arguments>
        grub .....
        The other thing that this patch does is it begins to make the
        multiboot 1 code a bit more architecture agnostic so IF someone wanted
        to implement it on another architecture they can.
        A bit of file moving around and definition renaming is also apart of
        this patch. I have also taken the time to make sure that it does not
        break multiboot 1 loading on i386-pc. But mulitboot 2 may still need a
        little more testing and work for i386-pc. Powerpc multiboot 2 has been
        heavily tested and does work.
