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.
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.

<sys/gpt.h>. This avoids having to include both <sys/uuid.h> and
<uuid.h>, which is considered by your friendly committer to be
aestheticly displeasing (= ballyhoo barf barf :-)
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).
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.
