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.

	* conf/i386-pc.rmk (kernel_img_SOURCES): Add `kern/time.c',
	`kern/i386/tsc.c', `kern/generic/rtc_get_time_ms.c' and
	`kern/generic/millisleep.c'.

	* kern/misc.c: Don't include
	<kern/time.h> anymore.
	(grub_millisleep_generic): Removed.

	* commands/sleep.c (grub_interruptible_millisleep): Uses
	grub_get_time_ms() instead of grub_get_rtc().

	get_time_ms() implementation.

	(ieee1275_get_time_ms): New function.
	(grub_machine_init): Install get_time_ms() implementation.

	* kern/i386/pc/init.c: Include <grub/cpu/tsc.h>.
	(grub_machine_init): Call grub_tsc_init().
	(grub_millisleep): Removed.
 
	* kern/ieee1275/init.c (grub_millisleep): Removed.
	(grub_machine_init): Install ieee1275_get_time_ms()
	implementation.
	(ieee1275_get_time_ms): New function.

* kern/i386/pc/init.c (make_install_device): Check for `grub_prefix'
        instead of `grub_install_dos_part' to determine whether a drive needs
        to be prepended to prefix (`grub_install_dos_part' is not reliable,
        because it can be overriden when loading GRUB via Multiboot).

        (grub_load_modules): Split out (and use) ...
        (grub_module_iterate): ... this function, which iterates through
        module objects and runs a hook.
        Comment out grub_mm_init_region() call, as it would cause non-ELF
        modules to be overwritten.

        * util/i386/pc/grub-mkimage.c (generate_image): Instead of appending
        the memdisk image in its own region, make it part of the module list.
        * util/elf/grub-mkimage.c (options): Add "memdisk"|'m' option.
        (main): Parse --memdisk|-m option, and pass user-provided path as
