This is a partition editor. While editing real disks
requires root, this is useful to create partitioned images for VMs.

+Fix disabling of libdevmapper.
+
+Fix bugs related to disabling libdevmapper. Parted is rarely compiled without

+sneaked in.

+Change 64-bit offset code to Android variant.
+
+Parted uses a workaround in case when off_t is 32-bit. This happens i.a.
+on arm android. Use android functions rather than syscall.
