Add support for device types and predictable device paths (rebased) (#257)
* Add better error logging on smartctl exec failure

We will now log a warning if smartctl path passed via command line is invalid.

Signed-off-by: Piotr Dobrowolski <admin@tastycode.pl>
(cherry picked from commit 1c9c6943e8)

* Add support for autoscan device types and predictable device paths

This adds a new command line option allowing for customization of
autodetected device types and enables use of special "by-id" device type
that forces use of predictable device paths (/dev/disk/by-id/...)

Relevant change to device name parsing regular expression is included
now, so predictable device paths are now also usable when directly
specified.
