Replace the contents of the tokens GQueue with a simple struct. This cuts the amount of memory allocated by tests/check-qjson from ~500MB to ~20MB, and the execution time from 600ms to 80ms on my laptop. Still a lot (some could be saved by using an intrusive list, such as QSIMPLEQ, instead of the GQueue), but the savings are already massive and the right thing to do would probably be to get rid of json-streamer completely.
