libquery: add optional handling of 'UI' ID pointers.

Handling those through different ways /might/ be needed sometimes, but
in most case this is just a nest of issues, since you can easily forget
to take them into account.

Note that this should be a 'non-functional' change, as this new behavior
is not used anywhere yet.
