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.

Even though we still have the "streamer" concept, the tokens can now
be deleted as they are read. While doing so convert from QList to
GQueue, since the next step will make tokens not a QObject and we
will have to do the conversion anyway.

JSONLexer only needs a simple resizable buffer. json-streamer.c
can allocate memory for each token instead of relying on reference
counting of QStrings.
