Log message:
	API change - support more const arg
	
	As dm_report_field_string() doesn't modify content of data pointer,
	it can be marked as const.
	
	It's slight API change - but doesn't require any change on the user side
	and supports wider range of arguments without const casting.
	(i.e. we may use as paramater const lv struct this way:  &lv->name)
