libfdisk: add API to control signatures wiping
Now libfdisk warns if another filesystem/RAID/PT signature is detected on the device. It seems better and user-friendly to make it possible to wipe the signatures when we write a new disk label to the device. This patch adds to the library API fdisk_enable_wipe() fdisk_has_wipe() fdisk_get_collision() to control this new feature. The device modification is done by libblkid (the same we use in some mkfs-like utils). Signed-off-by: Karel Zak <kzak@redhat.com>
