Maybe we could make QAPI support generic filtering for all query-*
commands. But there's still a cost with making all query-* commands
malloc the space for an entire list only to then have a QAPI layer on
top of it do filtering before handing back the single element over the
wire, compared to passing the filtering down to the query-*
implementation to do the filtering in place.
