Newer versions (dmraid-1.0.0-rc16?) of dmraid default to always
creating partition names by inserting the letter 'p' between the
device name and the partition number. Since this is not
consistent with older versions of dmraid, add extra logic to
ensure that newer versions of dmraid do not insert this extra
letter 'p'.
Rename method get_udev_name to get_udev_dm_name and enhance to
retrieve the property DM_NAME.
Handle situation where parted, and hence libparted, has been
configured with --disable-device-mapper. In this situation on
some distros the device name could be /dev/dm-0. This results in
invalid partition names such as /dev/dm-0p1. Add logic to decode
the actual /dev/mapper name.
With this patch the commands required to support motherboard BIOS
RAID, also known as fake RAID, are dmraid and dmsetup.
If the kpartx command is available, it will be used to maintain
device entries that follow the naming convention used by kpartx.

devices

This patch along with a few preceding patches address the
following bug reports:
Closes bug #622217 - gparted live 0.6.0-1 incompatibility with
AMD RAID (SB750 southbridge)
Closes Ubuntu launchpad bug 600729 - Gparted not usable on
fakeraid arrays

Prevent overwriting meta data (Extended Boot Rectors) for logical
partitions by temporarily increasing the size of the logical
partition to encompass all of the space involved in the move
operation. The libparted library will move the EBR as needed to
permit this to happen. After the move the logical partition is
set to the proper size.
This fixes bug #623630 - Move logical partition to right yields
invalid partition table on /dev/sda - wrong signature 0
