BER object tree traversal to walk a shared borrow of a BER object

When implementing your own visitor, define your own visit_ber_xxx methods.

Note that visit_ber is called for every object, so if you implement multiple visitor methods they will be called multiple times for the same object. Generally, if visit_ber is implemented, then other methods are not needed.

For example, on a Sequence item, visit_ber is called first, then visit_ber_sequence, and then visit_ber for every sequence object (recursively).

Entry point: use the Visit::run or Visit::run_at methods.
