In case no BOM is present in the CSV file the utf-16 codec won't work.
We fail over to utf-16-le as Little Endian is commonly used.
NOTE: The original change landed this fix in efi_utils.py, however
that was introduced after the Xena development cycle, so this
backport moves the original change to where the code originally
came from to populate the efi_utils.py file.

In the event a device name is set to contain a raid device path, it is possible for the Name and Events field values of mdadm's detailed output to contain text which inadvertently gets captured and mapped as component data for the "holder" devices of the RAID set. This would cause invalid values to get passed to UEFI methods which would cause a deployment to fail under these circumstances. We now ignore the Name and Events fields in mdadm output.

UDev prefix is DM_ not ID_ for them. On top of that, they don't have short serials (or at least don't always have). Change-Id: I5b6075fbff72201a2fd620f789978acceafc417b (cherry picked from commit 69e22545033f544d628f9c4ecd5a665ba0b5b85e)
Removes multipath base devices from consideration by default, and instead allows the device-mapper device managed by multipath to be picked up and utilized instead. In effect, allowing us to ignore standby paths *and* leverage multiple concurrent IO paths if so offered via ALUA. In reality, anyone who has previously built IPA with multipath tooling might not have encountered issues previously because they used Active/Active SAN storage environments. They would have worked because the IO lock would have been exchanged between controllers and paths. However, Active/Passive environments will block passive paths from access, ultimately preventing new locks from being established without proper negotiation. Ultimately requiring multipathing *and* the agent to be smart enough to know to disqualify underlying paths to backend storage volumes. An additional benefit of this is active/active MPIO devices will, as long as ``multipath`` is present inside the ramdisk, no longer possibly result in duplicate IO wipes occuring accross numerous devices.

The existing lsblk call is very handy for an overview, but there a lot more useful pairs to collect. Collect them in a machine-readable format to be able to use in debugging and further development.

Using partition numbers is currently broken for devicemapper devices. Fortunately, GPT has partition UUIDs, so we can just generate one and use it for lookup. NOTE on backport: _get_partition is imported from the image extension. In Yoga it was moved to partition_utils.

The logic of adding a partition number to the device path does not work for devicemapper devices (e.g. a multipath storage device).
