Use g_ alloced memory (instead of emem) when printing fields. emem shouldn't be used for GUI functions anyway.
emem was exposed because of its memory limits trying to output PDML for a very large byte field in a capture file.
When converting from proto_construct_match_selected_string to fvalue_to_string_repr remember proto_construct_match_selected_string includes fieldname + value, not just value
