a565cc2897 Write the MBR by using the bootcode verb of the gpart class.
The "write MBR" verb is kept for backward compatibility, but
the DIOCSMBR ioctl has been removed.

ae3096705c Another, hopefully final set of changes to boot0 and boot0cfg.
boot0.S changes:

+ import a patch from Christoph Mallon to rearrange the various
  print functions and save another couple of bytes;

+ implement the suggestion in PR 70531 to enable booting from
  any valid partition because even the extended partitions that
  were previously in our kill list may contain a valid boot loader.
  This simplifies the code and saves some bytes;

+ followwing up PR 127764, implement conditional code to preserve
  the 'Volume ID' which might be used by other OS (NT, XP, Vista)
  and is located at offset 0x1b8. This requires a relocation of the
  parameter block within the boot sector -- there is no other
  possible workaround.
  To address this, boot0cfg has been updated to handle both
  versions of the boot code;

+ slightly rearrange the strings printed in the menus to make
  the code buildable with all options. Given the tight memory
  budget, this means that with certain options we need to
  shrink or remove certain labels.

and especially:

	make -DVOLUME_LABEL -DPXE the default options.

  This means that the newly built boot0 block will preserve the
  Volume ID, and has the (hidden) option F6 to boot from INT18/PXE.
  I think the extra functionality is well worth the change.

  The most visible difference here is that the 'Default: ' string
  now becomes 'Boot: ' (it can be reverted to the old value
  but then we need to nuke 1/2 partition name or entries to
  make up for the extra room).

boot0cfg changes:

+ modify the code to recognise the new boot0 structure (with the
  relocated options block to make room for the Volume id).

+ add two options, '-i xxxx-xxxx' to set the volume ID, -e c
  to modify the character printed in case of bad input

3bb24c35f2 Split MBR and PC98 on-disk sliceformats out from disklabel.h, step 1:
Peter had repocopied sys/disklabel.h to sys/diskpc98.h and sys/diskmbr.h.

These two new copies are still intact copies of disklabel.h and
therefore protected by #ifndef _SYS_DISKLABEL_H_ so #including them
in programs which already include <sys.disklabel.h> is currently a
no-op.

This commit adds a number of such #includes.

Once I have verified that I have fixed all the places which need fixing,
I will commit the updated versions of the three #include files.

c5dc421f98 - When we save the existing MBR to a file, check to see if the MBR we are
saving is boot0.  If it is, use its version number so that we can grab
  all of boot0 (1024 bytes with version 1.1 for example) when we save it
  to a file via the 'f' option.  Otherwise, we just save the first sector.
- Cleanup this code a bit by splitting some functionality out into separate
  functions.

226ae6ffd3 Update boot0cfg to handle the new boot0:
- Allow for boot0 to be more than one sector long.  However, ensure that it
  its length is a multiple of the sector length.
- Change the signatures used to determine a valid boot0 as some of the
  signature code changed.
- Use the old signature to detect version 1.0 of boot0, otherwise read the
  version number from boot0 itself.
