+Parses given cookie value and extracts any udev control flags encoded.
+The output is in environment key format that is suitable for use in udev
+rules. If the flag has its symbolic name assigned then the ouput is
+DM_UDEV_FLAG_<flag_name>='1', DM_UDEV_FLAG<flag_position>='1' otherwise.
+Subsystem udev flags don't have symbolic names assigned and these ones are
+always reported as DM_SUBSYSTEM_UDEV_FLAG<flag_position>='1'. There are
+16 udev flags altogether.
