Subject: [PATCH] Add duplicate functionality to dasd type lables.
* libparted/labels/dasd.c (dasd_alloc): Add the errno to the exception
message to ease debugging.
(dasd_partition_duplicate): New function.
(dasd_duplicate): Include all the dasd specific structures in the
duplicate disk.
(dasd_partition_new): Handle the case when malloc fails because of lack
of memory.
(dasd_disk_ops): Add the new dasd_partition_duplicate hook.

Subject: [PATCH] Add disk as an argument to partition_duplicate.
The disk is needed to provide some context when creating the duplicate
partition. The disk is needed by the dasd type labels.
* include/parted/disk.h (partition_duplicate): Add the disk to the
function definition
* libparted/disk.c (_add_duplicate_part): Pass the "new disk" to the
partition_duplicate function.
* libparted/labels/aix.c (aix_partition_duplicate): Comply with the new
partition_duplicate function definition.
* libparted/labels/bsd.c (bsd_partition_duplicate): Likewise
* libparted/labels/dos.c (msdos_partition_duplicate): Likewise
* libparted/labels/dvh.c (dvh_partition_duplicate): Likewise
* libparted/labels/gpt.c (gpt_partition_duplicate): Likewise
* libparted/labels/loop.c (loop_partition_duplicate): Likewise
* libparted/labels/mac.c (mac_partition_duplicate): Likewise
* libparted/labels/pc98.c (pc98_partition_duplicate): Likewise
* libparted/labels/rdb.c (amiga_partition_duplicate): Likewise
