c69a7a718d Fix fdisk(8) to create 2TB partitions on disks larger than 2TB, rather than
only being able to create 1TB partitions:
o) Use an unsigned 32-bit quantity to store the number of disk sectors.
o) Detect overflow of said 32-bit quantity and clamp to 2^32.
o) Rather than returning the disk sector count from get_params, return 0 on
   success, since its return value is only ever compared to -1 to detect
   failure.  This would cause returning 2^32 sectors to be interpreted as an
   error.

fd1ca22afb Improve error reporting when MBR can not be written.
Remove obsolete code which uses DIOCSMBR ioctl.
When writing MBR first check that GEOM_MBR is available, if it is not
available, then try write MBR directly to provider. If both are failed,
then recommend to use gpart(8).

6bfcd9c37b The decimal() function was changed in r217808 to take the
maximum value instead of number of bits. But for case when
limitation is not needed it erroneously skips conversion to
number and always returns zero. So, don't skip conversion
for case when limitation is not needed.

f9373bbdac The MBR uses a 32-bit unsigned integer to store the size of a slice, but
fdisk(1) internally uses a signed int.  Should a user attempt to specify
a slice containing more than 2^31 - 1 sectors, an error will be reported
on systems with sizeof(long) == 4 and the slice size will be silently
truncated on systems with sizeof(long) > 4.

Instead use an unsigned long to store the slice size in fdisk(1).  This
allows the user to specify a slice size up to the maximum permitted by
the MBR on-disk format and does not have any problems with silent
truncation should the use specify an slice size larger than 2^32 on systems
with sizeof(long) > 4.

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Most entries in the table are probably 15+ years old and largely outdated,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.

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.
