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.

implementation.
(ieee1275_get_time_ms): New function.
(grub_get_rtc): Now calls ieee1275_get_time_ms(), which does the
real work.
* include/grub/i386/pc/kernel.h: Define GRUB_KERNEL_MACHINE_DATA_END to
indicate end of data section in kernel image.
* include/grub/i386/efi/kernel.h: Define GRUB_KERNEL_MACHINE_PREFIX and
GRUB_KERNEL_MACHINE_DATA_END.
* kern/i386/pc/startup.S: Do not initialize grub_prefix, only reserve
space for it.
* kern/i386/efi/startup.S: Likewise.
* util/i386/pc/grub-mkimage.c: Initialize grub_prefix to /boot/grub

patch.

code to make path relative to its root into a separate function.

make_system_path_relative_to_its_root() to convert ${grubdir}, then
pass the result to grub-install --prefix.
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.
