Add support for setting device friendly name using --set-name
My Videohub Micro doesn't support this extra but I suppose the
bigger models do (at least the official software v6 reads this
value and shows it instead of the device model).
Add support for --list-proc-units and --list-frames options.
--list-proc-units was documented in 1.0 release but it was never
wired up to work. --list-frames was not documented in 1.0 and it
wasn't working either.
