fdisk: add GPT support
This patch allows fdisk to handle GUID partition tables, based on the latest UEFI specifications
version 2.3.1, from June 27th, 2012. The following operations are supported:
- Probing (detects both protective and hybrid MBRs)
- Writing to disk
- Listing used partitions
- Adding partitions
- Deleting partitions
- Data integrity verifications (for both headers and partitions).
A few considerations:
- Currently we do not fix invalid primary headers -- we just abort!
- Header checksums are updated upon every change (ie: add/delete partitions), this allows us
to mathematically verify the changes on-the-fly, and not only when writing to disk, like
most other related tools do.
- We are extremly picky when writing to disk, any error aborts the opeartion.
- When creating a new partition, the following GUIDs are available:
http://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_type_GUIDs
For test cases, the gpt.img from libblkid tests, scsi_debug and my own hard drive (/dev/sda) were used.
For the image, all operations were tested successfully, and for /dev/sda all except write, which
was not tested - hey, I'm not suicidal!
[kzak@redhat.com: - add get/set partition type functions
- use unified on strings based table for partition types
- add partition type to table list function]
