High resolution timer support. Implemented for x86 CPUs using TSC.
Extracted generic grub_millisleep() so it's linked in only as needed.
This requires a Pentium compatible CPU; if the RDTSC instruction is
not supported, then it falls back on the generic grub_get_time_ms()
implementation that uses the machine's RTC.

(grub_load_modules): Split out (and use) ...
(grub_module_iterate): ... this function, which iterates through

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.

the beginning of the prefix.

It is assumed that if we have a memdisk, grub-mkimage has set
grub_prefix to include the "(memdisk)" drive in it.

a constant (same value).

GRUB_KERNEL_MACHINE_RAW_SIZE. Speed is not as important in this
code as correctness and size.
* kern/i386/pc/startup.S
(grub_biosdisk_get_diskinfo_int13_extensions): When converting
data block address to the real mode, keep offset minimal. This
works around a bug in AWARD BIOS on old Athlon systems, which

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
anything.
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.

* include/grub/i386/linux.h (struct linux_kernel_params): New
struct.
A new machine-specific function "grub_machine_set_prefix" is
defined. This is called after loading modules, so that a prefix
initialization can use modules. Also, this change adds an
intensive debugging feature for the memory manager via the
configure option "--enable-mm-debug".

PART.LEN.

[MM_DEBUG] (grub_debug_memalign): New function.
* kern/misc.c (grub_abort): Print a newline to distinguish
the message.
* kern/main.c (grub_main): Call grub_machine_set_prefix and
grub_set_root_dev after loading modules. This is necessary when
setting a prefix depends on modules.
* include/grub/efi/efi.h (grub_print_device_path): Renamed to ...
(grub_efi_print_device_path): ... this.
(grub_efi_get_filename): New prototype.
(grub_efi_set_prefix): Likewise.

* disk/efi/efidisk.c: Include grub/partition.h.
(iterate_child_devices): New function.
(add_device): First, compare only last device path nodes, so that
devices are sorted by the types.
(grub_efidisk_get_device_handle): New function.
(grub_efidisk_get_device_name): Likewise.
* configure.ac (--enable-mm-debug): New option to enable the
memory manager debugging feature. This makes the binary much
bigger, so is disabled by default.
