Applied, with some changes (add string based list of partition
types).
TODO:
- differentiate between number of allocated and used partitions in GPT,
for example "Partition number (1-128):" dialog is strange if you have
only one partition. [I'll fix it tomorrow]
- add 'Device' column to GPT list_table output [I'll fix it tomorrow]
- add 'g' to main menu to create a new empty GPT disklabel
- LBA alignment, it necessary to use the same things we use for MBR;
partitions has to be aligned according to I/O limits (sector
size). [Important!]
- move list_table() functions to fdisk_label drive struct
- remove 'disklabel' from fdisk.c at all and keep fdisk.c
independent on MBR
- remove global label-specific variables (e.g. gpt ents[])
- test GPT (specially 't' command) on big-endian machine
(EFI UUIDs has been designed during LSD trip...)
less important things:
- add '<something>' to fdisk menu to print details about selected
partition (uuid, type uuid, type name, name, etc...)
- add '<something>' to menu to print details about the partition
table (header, backup header, locations, number of allocated
entries, used entries, offset of entry table and offset and size
of data area, etc.)
All should be implemented by drive specific functions, without
exceptions, fdisk.c has to be simple and readable :-)
Note I did not applied the man page yet. I think we can do that
later when the code will be stable.

Yes, but this is not so important for now. We have to clean up before
we start to implement new things.
Thanks!
