The GValueArray type was added in a time, during the Jurassic era or so,
when GArray did not have a representable GType. The GValueArray API has
various issues as well:
- it doesn't match the other GLib array types;
- it is not reference counted;
- the structure is fully exposed on the stack, so it cannot be
extended to add reference counting;
- it cannot be forcibly resized.
The nice thing is that now we have a GArray type that can replace in
full GValueArray, so we can deprecate the latter, and reduce the
complexity in GLib, application code, and bindings.
