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).
