disklabel(8): convert malloc(x * y) to reallocarr

PR/50729: Izumi Tsutsui: Add "SMALLPROG"-like options to disklabel(8)

resync from head

Make disklabel a MI tool.  It will use MACHINE/MACHINE_ARCH to determine
the disklabel params as well as allowing command-line options of -M <machine>
and -B {le,be} to specify MACHINE and byteorder to be used.

move dk_ioctl to a header file for the benefit of x-building.

- simplify getinput.
- add adjust command.

bring matt-nb5-mips64 up to date with netbsd-5-1-RELEASE (except compat).

Change printf formats to match the data type of the values being
printed.  There's now a lot of PRIu16 and PRIu32, some PRIu8, some
SCNu32, and a few cases where %u and %d were reversed.  Multiplication
of 32-bit and 8-bit values is cast to uint64_t and printed with PRIu64.

Inspired by a report from Patrick Welche on current-users.

Change getnum() to use intmax_t instead of int, so it doesn't overflow
between 2^31 and 2^32. Adjust call sites accordingly. PR 43354.

- Display "Enter '?' for help" when starting interactive mode
- Use %.40g rather than %g when printing sectors and MB for existing
  partition size/offset.

Remove 3rd and 4th clauses in christos' license.  OK christos.

Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html

fix sign-compare issues

Add a '-l' flag and a 'L' command to interactive mode to list all known
file system types.  (Similar to what fdisk does for partition types.)

Closes PR bin/12954.

Avoid indexing beyond the end of a malloced array.
Rework loop to be less confusing.
Coverty 519 made me read this code, but this isn't the 'bug' it found.

Gracefully handle out of memory condition.

Rototil the way disklabel -r reads and writes labels.
In particular the 'read' part plays 'hunt the disklabel' in order to get a
label into a local buffer - from where it can be displayed/edited.
The 'write' part makes a separate scan of the disk looking for places to
write the label.
The main changes are:
- It can no longer write the first 8k of the mbr to the pbr (or v.v.)
- All labels on the disk (that it can find) get updated during a write
- With -A all the labels are displayed (inc. those deleted by -D)
- Addition of -D which will delete (by one's complimenting dk_magic{2}) and
  existing labels before writing labels to the expected locations.
- -v gives some verbose output to stderr, -vv more etc
A better basis for processing incorrect endian labels, or labels from other
architectures.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Make disklabel(8) into a host-tool, "nbdisklabel."  Move disklabel.c
to main.c to avoid a name collision with lib/libc/gen/disklabel.c
when we build nbdisklabel.  Still todo: commit host-tool build
infrastructure to src/tools/disklabel/.

Recognize more units and be more helpful when we enter bad units.

Add missing ' in prompt text.
Pointed out by Allen Briggs.

Add the ability to define a partition as starting after another partition.
If chaining is on, display all changed partitions (not just this one).

OK'ed by Christos.

Handle partition offset and size as unsigned entities.

Pull up revision 1.20 (requested by grant in ticket #402):
disallow creation of partitions which start beyond (or extend beyond)
the end of the disk.

disallow creation of partitions which start beyond (or extend beyond)
the end of the disk.

minor WARNS=2 stuff

- KNF printlabel.c
- add a function to print only one partition's info.
- print the partition information if it was modified in interactive mode.
- improve on the chaining code. [still assumes that partition offsets increase
  monotonically]. We could check for overlap too.

Pull up revisions 1.16-1.17 (requested by lukem):
  Several fixes and enhancements:
  o with ``-I'', initialize the label if it's not there, it's
    corrupt, or there's no ``fake'' label.
  o correct partition table header
  o move some functions into a separate file for other programs
    to use
  o fix examples and cross references
  o various cleanups

move showinfo() and showpartition() into separate file, for use by
other programs.  slightly change argument signature so that globals
aren't depended upon.

- convert to KNF ANSI style guide
- reorder arguments of runcmd(), getnum(), defnum() to be consistent
  with other functions (pass struct disklabel * first)

Pullup 1.13-1.15 [christos]:
supported disk types printout, sizeof parentheses, better error messages.

in cmd_name(), put the default prompt into a temporary buffer rather
than overwrite the existing d_packname.  noted by enami@.

* use strcasecmp() instead of strcmp() so that filesystem type and disk type
  searchs (amongst others) are case insensitive.
* in interactive mode (-i), when editing entries display supported disk types
  and filesystem types when given `?' (when ``[?]'' appears in the prompt
  this feature is supported for the question).
* support `m' as a suffix equivalent to `M'
* in interactive mode, be a bit more sensible about handling errors and EOF
* implement dumpnames(), which takes a char ** and size, and displays
  as per ls -F (sorted, listed vertically) but indented by one tab
* don't assume d_typename and d_packname are NUL terminated
* fix up some comments and some warning messages (bad cut & pastos :)
* deprecate deffstypename() and getfstypename()
* be consistent when using sizeof()

Pull up to last week's -current.

Pull up revisions 1.12-1.13 (requested by abs):
  When setting size of partitions interactively, allow '$'
  for the remainder of the disk.

Use '$' instead of '-' to select remainder of disk interactively

When setting size of partitions interactively allow '-' for remainder of disk

allow changing partition info from inside the interactive handler.

Pull up revision 1.10:
  'Label disk?' prompt should check for 'Y' as well as 'y'.  (abs)

Accept 'Y' for label disk as well as 'y'

Add a 'chain' command in interactive mode that allows you to vary the
size of the partitions, while the starting point gets adjusted automagically.
This chaining works for partitions that are not 'unused'.

Adjust for DKTYPENAME changes.

The number of fs types is FSMAXTYPES not DKMAXTYPES.
Correct read of formatted file (used with -e or -R) so that fstype with
spaces will work. Also enlarge the fstype field by 2 chars so that
"Linux Ext2" will not be truncated.

Don't pass return value of writelabel() to strerror(), since
the value is not a errno but just 0 or 1.

Fix warnings.

Off by one.

fix reversed test for maxpartitions.

Jason says: Use getmaxpartitions(3) to determine the number of partitions
allowed in this architecture.

Add -i (interactive mode to create/edit labels) inspired by the SunOS/Solaris
format/partition command.
