* use separate function to get free space
* allow to use label-specific get_freespace() function
(this is necessary for MBR extended partitions mess)

__sighandler_t is libc implementation specific and should not be relied
upon. Instead, we fall back upon void (*)(int), as specified by POSIX.

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:

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]

- 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
