json: Fix streamer not to ignore trailing unterminated structures
json_message_process_token() accumulates tokens until it got the
sequence of tokens that comprise a single JSON value (it counts curly
braces and square brackets to decide). It feeds those token sequences
to json_parser_parse(). If a non-empty sequence of tokens remains at
the end of the parse, it's silently ignored. check-qjson.c cases
unterminated_array(), unterminated_array_comma(), unterminated_dict(),
unterminated_dict_comma() demonstrate this bug.
Fix as follows. Introduce a JSON_END_OF_INPUT token. When the
streamer receives it, it feeds the accumulated tokens to
json_parser_parse().
