update from HEAD

add "prekern" to the string list.

Add a new option in libsa, to load dynamic binaries. A separate function
is used, and it does not break in any way the generic static loader. Then,
add a new "pkboot" command in the x86 bootloader, which boots a
GENERIC_KASLR kernel via the prekern. (See thread on tech-kern@.)

the x86 bootloader.

Complete the dosparts -> mbrparts conversion. Only x86k new uses dosparts

Add support for passing saved entropy (random seed file) to the kernel
from the bootloader.  This can fix the problem of poor quality keys
for other kernel modules which call arc4random() early in kernel startup
(NFS startup, in particular, causes this).

We continue to rely on the etc/rc.d/random_seed script to save entropy
to the seed file at shutdown and erase the seed file at startup.

Boot loader support implemented only for i386 and amd64 ports for now but
it should be easy for other ports to do the same or similar.

Sync with HEAD. TODO before merge:
- shortcut for suspend code in sysmon, when powerd(8) is not running.
Borrow ``xs_watch'' thread context?
- bug hunting in xbd + xennet resume. Rings are currently thrashed upon
resume, so current implementation force flush them on suspend. It's not
really needed.

Pass the VBE mode number from the bootloader to the kernel, and then
make the ACPI wakecode aware of it. Restore the desired VBE mode on resume
when acpi_vbios_reset=1, so suspend/resume with genfb console will work.

- Give x86 BIOS boot the ability to load new style modules and pass them
  into the kernel. Based on a patch by jmcneill@, with many fixes and
  improvements by me.

- Put MEMORY_DISK_DYNAMIC and MODULAR into the GENERIC kernels, so that
  you can load miniroot.kmod from the boot blocks and boot into the
  installer!

Implement support for 'The Multiboot Specification' so that i386 kernels
can be booted directly from Multiboot-compliant boot loaders (e.g. GRUB).
See the added multiboot(8) manual page for more information.

No objections in tech-kern@; only positive comments.

Add a 'struct bootinfo' to represent the bootinfo structure used in the
kernel by x86 platforms (instead of a simple char *).  This way, the code
in, e.g., lookup_bootinfo, is a bit easier to understand.

While here, move the lookup_bootinfo function used in x86 platforms (amd64,
i386 and xen) to a common file (x86/x86_machdep.c), as it was exactly the
same in all of them.

Make disklabel(8) and fdisk(8) into "host tools " last step:  build
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/.  That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such.  I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.

Nuke __P().

Overhaul MBR handling (part 1):

<sys/bootblock.h>:
    *	Added definitions for the Master Boot Record (MBR) used by
	a variety of systems (primarily i386), including the format
	of the BIOS Parameter Block (BPB).
	This information was cribbed from a variety of sources
	including <sys/disklabel_mbr.h> which this is a superset of.

	As part of this, some data structure elements and #defines
	were renamed to be more "namespace friendly" and consistent
	with other bootblocks and MBR documentation.
	Update all uses of the old names to the new names.

<sys/disklabel_mbr.h>:
    *	Deprecated in favor of <sys/bootblock.h> (the latter is more
	"host tool" friendly).

amd64 & i386:
    *	Renamed /usr/mdec/bootxx_dosfs to /usr/mdec/bootxx_msdos, to
	be consistent with the naming convention of the msdosfs tools.

    *	Removed /usr/mdec/bootxx_ufs, as it's equivalent to bootxx_ffsv1
	and it's confusing to have two functionally equivalent bootblocks,
	especially given that "ufs" has multiple meanings (it could be
	a synonym for "ffs", or the group of ffs/lfs/ext2fs file systems).

    *	Rework pbr.S (the first sector of bootxx_*):
	    +	Ensure that BPB (bytes 11..89) and the partition table
		(bytes 446..509) do not contain code.
	    +	Add support for booting from FAT partitions if BOOT_FROM_FAT
		is defined.  (Only set for bootxx_msdos).
	    +	Remove "dummy" partition 3; if people want to installboot(8)
		these to the start of the disk they can use fdisk(8) to
		create a real MBR partition table...
	    +	Compile with TERSE_ERROR so it fits because of the above.
		Whilst this is less user friendly, I feel it's important
		to have a valid partition table and BPB in the MBR/PBR.

    *	Renamed /usr/mdec/biosboot to /usr/mdec/boot, to be consistent
	with other platforms.

    *	Enable SUPPORT_DOSFS in /usr/mdec/boot (stage2), so that
    	we can boot off FAT partitions.

    *	Crank version of /usr/mdec/boot to 3.1, and fix some of the other
	entries in the version file.

installboot(8) (i386):
    *	Read the existing MBR of the filesystem and retain the BIOS
    	Parameter Block (BPB) in bytes 11..89 and the MBR partition
	table in bytes 446..509.  (Previously installboot(8) would
	trash those two sections of the MBR.)

mbrlabel(8):
    *	Use sys/lib/libkern/xlat_mbr_fstype.c instead of homegrown code
	to map the MBR partition type to the NetBSD disklabel type.


Test built "make release" for i386, and new bootblocks verified to work
(even off FAT!).

Add definitions (#defined out) to pass the result of the v3.x bios
extended disk information request to the kernel.
Binary compatible with the existing code, disabled because I don't
have a system with a bios that supports the request.

Move some files out of i386 into x86, so that they can be shared with
other ports.
