Get rid of it as a global variable as it belongs in the context.
To compare a disklabel on the device, the fdisk_dev_is_disklabel()
function is introduced. Also, to avoid naming issues, the fdisk_labeltype
members where renamed to FDISK_DISKLABEL_<type>.

The generic fdisk_delete_partition() function returns 0 when a partition
is correctly deleted, otherwise it's corresponding error (negative values).
This, however, does not include problems that can occur in actual label
specific contexts, so we need to propagate the corresponding return code,
back to the user visible api.

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]
