Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
Linux from around 5.6 now enumerates individual disks in any order
(whereas previously it enumerated only drivers in parallel). This
means that /dev/sdX ordering is no longer stable - in particular we
cannot be sure that /dev/sda inside the guest is the first disk that
was attached to the appliance, /dev/sdb the second disk and so on.
However we can still use SCSI PCI device numbering as found in
/dev/disk/by-path. Use this to translate device names in and out of
the appliance.

For Device parameters we expect a block device name. However we were
only testing for "/dev/..." and so chardevs (from the appliance) could
be passed here, resulting in strange effects. This adds a function
is_device_parameter which tests for a valid block device name.
For Dev_or_Path parameters much the same, except we can also use the
is_device_parameter function elsewhere in the daemon to distinguish if
we were called with a device or path parameter. Previously we used a
simple test if the path begins with "/dev/...".
