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!

- move MBR partition types to dos_part_types.h
- make dos_part_types.h independent on datetypes to keep it useful in
all fdisks
- add struct fdisk_parrtype
- move label specific partition types to context->label

Commit 79c8a145dd changed the numerical values of
fdisk_labeltype and broke the menu functionality, mixing main and expert menus.
Revert this change along with the label comment regarding it matching labeltype.
This is no longer valid since the original patch that lead to this modification
assumed that __probe_labels() would use these indices when creating a default
DOS/SUN disklabel, see http://www.spinics.net/lists/util-linux-ng/msg06509.html

The context structure is the fdisk API's main data type as it keeps all data
together. Add the label structure to it, so that the pt-specific operations can
be called from the context.

This patch sets the initial layout for label specific operations. A
new fdisk_label structure is created that will hold all these ops,
like new, delete, write and probe, among others. For now only probing
is implemented. Once this design is established, a copy of the probed
label will be copied to the main context structure, where calling the
specific functions will save 'disklabel' checks. Debugging support is
added as well.
This patch passes regression tests and manually passes bsd, sun, dos
and sgi labels probes.
