68df7abe8a Warn user when value entered is greated than the amount supported
by the MBR for the given parameter and set that parameter to the
maximum value instead of just truncating the most significant part
silently.

Could happen for example if the capacity of the device is more
than 2TB, so that the number of sectors is greater than 2Mib.

22fccf5ce9 Another change from Christoph:
replace the table of partition with a simpler and faster array of strings.
The change in the array is done mechanically, using vi commands.
Most entries in the table are probably 15+ years old and largely outdated,
so the next step is to remove stale entries with more current values.

c4898ccb7c Some small fixes submitted by Christoph Mallon, specifically:
+ Remove a dead field of a struct. It serves no purpose anymore.
+ Remove a \n at the end of the format string of err(); the err()
  function already adds a \n ;
+ remove many unnecessary casts which obfuscate the code.

This file has a huge number of indentation bugs, but I'd rather fix
them when/if we happen to modify the relevant parts of the code.

duplication of code in fdisk and boot0cfg. Also make use of g_providername to

aee85526aa - Fail with an understandable error message if we cannot detect the
sector size, instead of later failing with an error about /boot/mbr
  not being a multiple of the sector size (since we end up with an
  assumed sector size of MAX_SEC_SIZE * 2).
- We query the sector size via an IOCTL anyway, so if that succeeds
  use that instead of probing for it via read(2) calls.  This fixes
  the problem with fdisk failing to operate on at least graid3 and
  md(4) devices on kernels with src/sys/geom/geom_dev.c before
  rev. 1.90, due to fdisk failing to detect the sector size.
- When detecting the root device allow "/" characters in it, which
  happens with e.g. gmirror devices.

1a03d6d57a Use symbolic constants from <sys/diskmbr.h> instead of local constants.
Always set the magic sequence when we write, rather than trusting the
previously read boot code to do so.

Use explicit encoding/decoding of little endian disk image.

Remove a comment which was OBE.

Change the test vector for "fdisk -I" to reflect that there is a magic
sequence in the result now.

Add test case for "fdisk" which reads the image back.

At least for the two test-cases this program now gives the same result
on sparc64 as on i386.  The lack of an installed /boot/mbr on sparc64
raises an (un)interesting question.

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.
