Subject: [PATCH 107/131] libparted: remove all old partitions, even if new
label allows less
We were limiting partition sync operations to the lesser number allowed
by the device, or the label. This meant that when creating a new label
over an old label that had more partitions than the new one allows, the
higher partitions would not be removed. Use the greater of the two values
for the remove pass, and the lesser for the add.

+ libparted: remove all old partitions, even if new label does not allow
+ as many.
+
libparted: fat and ntfs boot sectors were misdetected as dos
partition tables instead of being treated as a loop label.
