Surpass 1 TiB disk addressing limit. Note: there are no plans to handle
the 2 TiB disk limit in GRUB Legacy, since that would need considerable
rework. If you have >2TiB disks, use GRUB 2 instead.
* grub/asmstub.c (biosdisk): Add unsigned qualifier to `sector'.
* stage2/bios.c (biosdisk): Likewise.
* stage2/disk_io.c (rawread, devread, rawwrite, devwrite): Likewise.
* stage2/shared.h (rawread, devread, rawwrite, devwrite): Likewise.
* lib/device.c (get_drive_geometry): Replace BLKGETSIZE with
BLKGETSIZE64.
* grub/asmstub.c (get_diskinfo): Toggle "kern.geom.debugflags" sysctl
before opening a device for writing.
* util/grub-install.in: Devices don't have this "r" prefix anymore.
* lib/device.c: Mangle __FreeBSD_* macro usage to support
kFreeBSD-based non-FreeBSD systems (i.e. GNU/kFreeBSD).
Implement runtime detection of version of kFreeBSD. Now if
we build against kFreeBSD 5.x headers the GRUB shell will work on
both 4.x and 5.x.
Replace `u_int_t' types with portable `unsigned int' and old
reference to `geometry' structure to new `geom' one.
* docs/menu.lst: Split GNU/kFreeBSD and GNU/kNetBSD as separate
options than FreeBSD and NetBSD, respectively. There are minor
differences now (different paths).
