- need user_data (the string/string-array)
- need a free_func for the user_data
- need a get_structure_func to fill structure slots as needed
- we can more easily make this iterator based too
- operations (e.g. intersect) (see [1]).

We should add PERFORMANCE category logging to methods that cause lazy caps to be
fully evaluated.
fully evaluated. To get maximum speed benefit we need to inspect places that
loop over structures of a caps and turn them into while() loops where possible.
We can use GST_CAPS_FLAGS_LAZY to indicate that caps are not fully constructed.
Once caps are fully evaluated, we can remove the flag (and call the free_func).
