c946bc9408 Fix cut-n-paste bug: compare argument s against known aliases,
not the global optarg. This bug goes unnoticed because optarg
is so far always the actual argument for the formal argument s.

d33cea825e Add support for setting GPT partition labels. The partitions to be
labeled are selected in the same way as with the remove command.
Update the manpage to have the selection options described for the
label command and referenced to it from the remove command.
The label can be specified on the command line with the -l option
or read from a file with the -f option. In both cases, the label
is assumed to be encoded in UTF-8.

7b637cbb7e Don't print the total number of partitions removed now that we print
the name of the partitions that we remove. A summary is unnecessary

e669069b43 - distinguish between the device name (what the user called it on the
command line) and the device path (what we passed to open()).  Use
  the former in diagnostics.
- when adding or removing partitions, print a single line to stdout for
  each partition that was added or removed, indicating its name.
- add an -a option to 'gpt remove' which must be explicitly specified
  to remove all partitions.

044a6050c4 Add an -f option (for force) to the migrate command. Normally an MBR
with unknown partitions is not migrated. By specifying the -f option
migration will happen and unknown partitions will be lost.

571405ddd6 Add an -f option (for force) to the create command. The -f option
allows the user to force the creation of a GPT even when there's a
MBR on the device. The MBR is simply wiped and any partitions
described by it are lost. Without the -f option one cannot create
a GPT when there's a MBR.

3dc93f0071 Fix a braino: the partition size in the PMBR is in sectors, not bytes
and 'mediasz' is in bytes. As it so happens, we define 'last' as the
sector number of the last sector on the medium which also is the size
of the PMBR partition. Therefore, use 'last' instead of 'mediasz'.

6972147914 Remove the -k option to migrate. The option causes gpt(8) to preserve
the MBR after it is migrated to a GPT. While this was useful during
the early days when GPT support was under development, it's something
that users can use without knowing what they're getting themselves
into. The possible harm outweights the marginal usefulness it now has.

aaf12b42bb Implement a remove command. The remove command iterates the GPT
partitions and removes any that matches the pre-conditions. The
options are the same for the add command and are used to select
the partitions to remove.
Currently the remove command without any options deletes all GPT
partitions. This is rather harmful and will need anti-footshooting
measures.

starts at 1. No index is represented by 0.
o  Change the show command to display the partition number at the expense
   of the partition end columm. We already display the start and size.
o  Enhance the add command to accept the -i option. The -i option allows
   the user to specify which partition number the new partition should
   get.
o  Update the manpage accordingly.

4abeaed33d o Newer EFI implementations require that a GPT is preceeded by
a PMBR. Make sure the create command creates a PMBR as well
   (if not already present).
o  When parsing the MBR, explicitly check for a PMBR and create
   a PMBR map node if one is found.
o  When parsing the MBR, recurse to handle extended partitions.
   This allows us to flatten nested MBRs when migrating to a
   GPT.
o  Have the migrate command bail out if it encounters a partition
   it doesn't know how to migrate. This avoids data loss.
o  Change the output of the show command so that the UUIDs of the
   GPT partitions fit on the same line.
o  Show when partitions are extended partitions and add the PMBR
   type.

29bcc6132f Allow aliases to be used when specifying partition types. The use of
UUIDs can then be limited to those cases when an alias doesn't exist.
This greatly increases the likelyhood that a sysadmin finishes the
partitioning without intermittent mental breakdowns. Current aliases
are "efi", "swap" and "ufs".

While here, staticize global variables and expand the usage message.

The default GPT partition type is UFS. When no starting block
or size are specified, the tool will create a partition in the
first free space it find (or that fits, depending on the size).

ca96817679 Don't complain if we have an inconsistent map that may be the
result of an incomplete migration. An incomplete migration is
one where the MBR is not turned into a PMBR after creating the
GPT. This early in the game it's more convenient to allow the
inconsistency, because that avoids that we have to destroy the
MBR partitioning for now.

6dfc24537d Grab a snapshot of Marcel's gpt tool. This is still a work-in-progress
but is useful to have handy.  EFI GPT partitions are used instead of the
fdisk+disklabel combination.  They are pure 64 bit LBA, are fully
extensible, support up to 16383 partitons per disk, etc.
