- Essentially no changes from current dissector de facto tvbuff usage;
- Do away with 'usage_counts' and with 'used_in' GSLists;
- Manage tvb chains via a simple doubly linked list.
- API changes:
a. tvb_increment_usage_count() and tvb_decrement_usage_count() no
longer exist;
b. tvb_free_chain() can only be called for the 'top-level' (initial)
tvb of a chain) or for a tvb not in a chain.
c. tvb_free() now just calls tvb_free_chain() [should have no impact
on existing dissectors].
