libfdisk: make it possible to use zero for size and start
The zero may be valid size and start of the partition. This patch
introduces:
fdisk_partition_has_start()
fdisk_partition_has_size()
fdisk_partition_unset_size()
fdisk_partition_unset_start()
to make it possible to work with zero. The feature is internally
implemented by magic constant ((type) -1) for undefined sizes and
offsets.
