7201d7b009 Show the paritition types that we recognize in human readable format. eg:
pluto2# gpt show da0
     start       end      size  contents
         0         0         1  PMBR
         1         1         1  Pri GPT header
         2        33        32  Pri GPT table
        34    401595    401562  GPT part - EFI System partition
    401596    925883    524288  GPT part - FreeBSD ufs partition
    925884   9314491   8388608  GPT part - FreeBSD swap partition
...
It'll print a plain uuid string for unrecognized types.

2a944ecdef 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.

1efbdbe23b Add a manpage. Nobody expects the spanish inquisition, but the
mdoc(7) police... It's all yours ru :-)

b103cd4113 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.

78edc0fda2 Remove inclusion of <sys/uuid.h>. We now include <sys/uuid.h> in
<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 :-)

c1fd52ba74 o Remove the fallback implementations of uuid_create(),
uuid_from_string(), uuid_is_nil() and uuid_to_string().
o  Include <uuid.h> where appropriate.

5d5e1c2b12 o Add functionality to add a GPT partition,
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).

e6f737b346 Add the functionality to create an (empty) GPT from scratch. The
code is directly copied from migrate.c. The intend is to express
migrate in terms of create and add. The functionality to add
partitions is not yet there.

fec26e0e4c 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.

80643c90e3 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.
