Add byte swapping and UUID encoding/decoding to allow gpt to be compiled on big-endian machines. Obtained from: Dan Markarian <markarian at apple dot com>

void le_uuid_dec(void const *, uuid_t *);
void le_uuid_enc(void *, uuid_t const *);
Move the duplicated logic of parsing partition types into a new function called parse_uuid().

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).

- 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.

int cmd_add(int, char *[]);
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.

int cmd_destroy(int, char *[]);
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. PR: ia64/83124 MFC after: 1 week

int cmd_migrate(int, char *[]);
int cmd_recover(int, char *[]);
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.
