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.

* kern/i386/pc/init.c (make_install_device): Check for `grub_prefix'
instead of `grub_install_dos_part' to determine whether a drive needs

because it can be overriden when loading GRUB via Multiboot).
* disk/memdisk.c (memdisk_size): Don't initialize.

(codestart): Don't add grub_memdisk_image_size to %ecx in LZMA
decompression routine (grub_total_module_size already includes that
now). Don't copy modules back to low memory.
* kern/main.c: Include `<grub/mm.h>'.
(grub_load_modules): Split out (and use) ...
(grub_module_iterate): ... this function, which iterates through
module objects and runs a hook.

the memdisk image in its own region, make it part of the module list.
* util/elf/grub-mkimage.c (options): Add "memdisk"|'m' option.

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.

ELF segments, use a macro for arbitrarily accessing any of them instead
of preparing a pointer that allows access to one at a time.
(grub_multiboot_load_elf64): Likewise.
* include/grub/i386/pc/kernel.h (GRUB_KERNEL_MACHINE_DATA_END):
Increase from 0x50 to 0x60.
* util/i386/pc/grub-install.in: Detect cross-disk installs, and
use UUIDs to identify the root drive for them. If that's not
possible, abort.
* util/i386/pc/grub-setup.c (setup): Do not special-case, or even
check, for cross-disk installs.

grub_console_gotoxy() to go back to beginning of the screen.

* util/update-grub.in: Add a check for admin
group on Cygwin.
Remove old `grub.cfg.new' before creation.
Add `-f' to `mv' to handle the different filesystem
semantics of Windows.

(struct grub_apple_header): New struct. Describes the layout of
the partmap header.

configure.ac or aclocal.m4 and runs autogen.sh.
