Eric Blake	55e1819c50	qobject: Simplify QObject The QObject hierarchy is small enough, and unlikely to grow further (since we only use it to map to JSON and already cover all JSON types), that we can simplify things by not tracking a separate vtable, but just inline the code element of the vtable QType directly into QObject (renamed to type), and track a separate array of destroy functions. We can drop qnull_destroy_obj() in the process. The remaining QObject subclasses must export their destructor. This also has the nice benefit of moving the typename 'QType' out of the way, so that the next patch can repurpose it for a nicer name for 'qtype_code'. The various objects are still the same size (so no change in cache line pressure), but now have less indirection (although I didn't bother benchmarking to see if there is a noticeable speedup, as we don't have hard evidence that this was in a performance hotspot in the first place). A future patch could drop the refcnt size to 32 bits for a smaller struct on 64-bit architectures, if desired (we have limits on the largest JSON that we are willing to parse, and will probably never need to take full advantage of a 64-bit refcnt).

Markus Armbruster	7f0278435d	qstring: Make conversion from QObject * accept null qobject_to_qstring() crashes on null, which is a trap for the unwary. Return null instead, and simplify a few callers.

Luiz Capitulino	66f7048712	Introduce QString QString is a high-level data type that can be used to represent C strings. The following functions are available: - qstring_from_str() Create a new QString - qstring_get_str() Get a pointer to the stored string Note that qstring_get_str() is too low-level for a data type like this, but it's interesting for quick read-only accesses.
