migration will happen and unknown partitions will be lost.

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.

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'.

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.

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.

While here:
o Make the UUIDs static to avoid runtime initialization,
o Rename ext to mslinux,
o Replace the use of memcmp() with uuid_equal(),
o Various style(9) improvements,
o Order the comparisons based on importance,
o Remove the word partition from all the descriptions,
o Other description improvements.

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.

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.

o Use DCE compliant UUID functions and provide local
implementations if they don't exist,
o Move dumping of the map to show.c and print the
partition type,
o Some cleanups and rearrangements.
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).

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.

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.
